| |
| Some partially corrupt mod files cause mikmod to try and allocate lots |
| of memory, this is ok, because failure to do so is being handled. |
| |
| But the new libmikmod malloc code align_pointer function did not handle |
| asking to align the NULL pointer, resulting from the too big alloc, |
| causing a segfault, this patch fixes this. |
