Running ``info files'' (in GDB, after the SEGFAULT happened) should tell
you how the memory regions are mapped. That might give some clue about
how to translate the addresses.

These look like (int) -1 displayed as 32-bit hex, or casted to (unsigned
int), or to a pointer. This may be what the author intended to do, or it
may be wrong -- I can't tell yet.

Please continue here: what is this function doing? (You didn't past that
