This is where you should start debugging: in frame #1 unexelf.c called
memcpy with bad arguments.  So the first thing to do is to find which
argument is bad, and then try to figure out why.

Therefore, please look at line 925 of unexelf.c and print the values
of the arguments it passes to memcpy.  One or more of them should be
wrong (e.g., NULL pointers etc.).
