    Free allocated space

    I'm calling a function that's allocating space and filling a char array.

    char **array;
    size = split(&array, string, delim);
    int split(char ***trgtArrray, char *string, char delim) {
      (*trgtArray) = (char **) malloc(count);
      return count;
    When I try to free **array it crashes. What am I doing wrong?

    Maybe, did you really do this?
    (*trgtArray) = (char **) malloc(count * sizeof(char*) );

    Also, see the FAQ on casting malloc in C programs.
    Are you secretly compiling this as a C++ program?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
