Does anyone know what this message refers to and how to correct the
problem.

I have a c program that runs and outputs the correct solution but I get
the above error messages from the following lines of code

        for ( i=0;i<1000;i++) {
        char=(char *)calloc(sizeof(char[MAX_LENGTH]),1)
                ...
        strcpy(char,"HELP")
                ...
        free(char)
        }

This does not happen every time in the loop.

Thanks,

Jeff
