free(ini->data) crashes on non-standard libc

[gpetersson]

Some non-standard libc's (such as on game SDKs or other embedded systems) do not do null checks before freeing memory. I think at least the free(ini->data) line in ini.c should have a check added there so there would not be a crash if a file is not found. Could this be done?

Thanks

As ini_load on success always allocates atleast '\0'¹ ini->data could never be NULL. However, what is missing is the check..

  ini->data = malloc(sz + 1);
  if (!ini->data) {
    goto fail;
  }

.. which would make sense to check for consistency as the malloc above² it is checked as well..

  ini = malloc(sizeof(*ini));
  if (!ini) {
    goto fail;
  }
