Patch to fix the bug

The reason was that in case if option -remap was specified pfile->file_hash 
was updated before attempt to use pointer hash_slot. If the array additionally 
gets reallocated then the result is accessing already freed memory. Calling 
htab_find_slot_with_hash once more later fixes the problem (verified for 
i586-pc-msdosdjgpp)
