int off_to_name = sizeof(long) + sizeof(off_t) + sizeof(short);
That's not reliable, though it seems to be working for you. Things an
be packed to different sizes when they are in structures than when
they are stand-alone.
Look up offsetof(), or at least use (size_t)(((struct linux_dirent*)0)->d_name)
/* array holding pointers to 5000 names */
char **allnames = (char **) GC_MALLOC(5000);
Not unless pointers are 1 byte on your machine.
So, this array is overflowing, as guessed by both of us.
