    The cause:

    This issue is probably hidden deep within your code, as stated in a comment. A zombie is the culprit that causes this error.

    Solution:

    The simplest way to solve this error is using culprit itself, zombie, (ideally on the most recent version of Xcode, which is Xcode 5 due to improvements) under profiler and select “Zombies”. You can view the history of everything that has ever happened to the item if it fails.

    You can also set a breakpoint for an exception as well. Instead of in main, where the exception is passed up, you may obtain a break when the issue occurs.

    Added an answer on June 29, 2022 at 12:23 am

    The cause: You have got this error because you are having 3 holes: 1st hole is  int numEntries. Then you do: ++numEntries; You are increasing the undefined values. Even if it is UB, it's still faulty. 2nd hole is: const int length = numEntries; int* arr = new int[length]; 3rd hole is: const int sizeRead more

    The cause:

    You have got this error because you are having 3 holes:

    1st hole is  int numEntries. Then you do: ++numEntries;

    You are increasing the undefined values. Even if it is UB, it’s still faulty.

    2nd hole is:

    const int length = numEntries;
    int* arr = new int[length];

    3rd hole is:

    const int size = numEntries;
    int matrix[size];

    numEntries (first hole) has undetermined values. It is Specified Behavior when you use it to initialize length and size. The std::bad alloc error indicates that you are attempting to allocate more memories than is currently available. However, let’s assume that it is just a large number and that you are allocating memory of an indeterminate amount (perhaps just a very large value).

    Additionally, the behavior of the matrix, which is undefined and non-standard, is a VLA of undefined size.

    These are the reasons of your error.

    Solution:

    You have to provide the specified values for numEntries, matrix and give enough memories for std::bad alloc.

    The cause:

    You encounter this error because you are attempting to make a temporary directory but you cannot write the file in that directory ialthough you have converted permissions.

    Solution:

    You can solve this error by altering the file’s extension. The code would only accept one extension, in spite of the fact that both of them were associated with the same file type. Sometimes all it asks is to restart the console or terminal, load the libraries once more time at startup. (Assumed that the GUI will work without saving or using a previous workspace).

    The cause: The software may not have been completely removed from your device since there may have been an issue when removing it.

    Do by 2 ways:

    2a)

    mysql -u root -p -h 127.0.0.1 -P 3306

    2b)

    mysql -u root -p -h > localhost -P 3306

    3) If the connection is strong, a password prompt will appear; try to connect using the right password. Whenever your connection is rejected, simply accept the permission.

    mysql >GRANT ALL ON [DatabaseName].* TO 'root'@'127.0.0.1' IDENTIFIED BY '[PASSWORD]';

    If your connection is recognized here, the issue is comparable to a workbench configuration issue.

    Added an answer on June 28, 2022 at 2:57 am

    The cause: You have got this error because you are having 8 columns but you only provide 7 collumn names for them. It shows up obviously in your program: > length(fcm) [1] 8 Or > ncol(data1) [1] 8 Even the matrix is shown: > data1 # [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] #fcm 14.0 14.1 13.Read more

    The cause:

    You have got this error because you are having 8 columns but you only provide 7 collumn names for them. It shows up obviously in your program:

    > length(fcm)
    [1] 8

    Or

    > ncol(data1)
    [1] 8

    Even the matrix is shown:

    > data1
    # [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
    #fcm 14.0 14.1 13.0 14 2.0 14.7 13.8 14.0
    #gk 12.1 12.5 12.2 12 0.0 11.5 12.0 11.4
    #gg 14.0 14.1 13.0 3 12.8 12.0 12.2 12.0

    At the time

    > length( c(6, 7, 8, 9, 10, 11, 12))
    [1] 7

    Solution:

    To solve this error, you can try:

    colnames(data1) <- c(6:13)

    Let’s do as the following command for your data:

    fcm <-c(14.0,14.1,13.0,14,2,14.7,13.8,14.0)
    gk <-c(12.1,12.5,12.2,12,0,11.5,12.0,11.4)
    gg <-c(14.0,14.1,13,3,12.8,12.0,12.2,12.0)
    data1 <- rbind(fcm,gk,gg)
    colnames(data1) <- c(6:13)

    Then, it gives the result without any error:

    > data1
    6 7 8 9 10 11 12 13
    fcm 14.0 14.1 13.0 14 2.0 14.7 13.8 14.0
    gk 12.1 12.5 12.2 12 0.0 11.5 12.0 11.4
    gg 14.0 14.1 13.0 3 12.8 12.0 12.2 12.0

    Your error has been fixed successfully.

    The cause:

    While developing or debugging a project of web application, the Microsoft Visual Studio 2010 IDE gets a trouble. The corrupted Cache of Visual Studio 2010 is the reason of this error.

    Solution:

    To solve this trouble, you have to exclude the csproj.user files. In other instances, you can fix this error by checking “Auto-assign Port” and “Use Visual Studio Development Server” on the Web tab of the project properties. After that, you must restart Visual Studio and recreate the project. Your program will work well.

    The cause: You are having a trouble with the error ''access denied for user ‘odbc’@’localhost’ (using password: no)'' because you do not determine an username and give it correct password, so it will try to connect with the ODBC username that does not exist.

    The cause:

    You are having a trouble with the error ”access denied for user ‘odbc’@’localhost’ (using password: no)” because you do not determine an username and give it correct password, so it will try to connect with the ODBC username that does not exist.

    Solution:

    You have to creat a definite username which you believe or in PHPMyAdmin you can create an ODBC user for MySQL without using a password.

    However, there is no problem in the case it’s only your local development environment. If it’s in your working environment, it will leave a significant security gap.
