           Summary: Internal error in peicode.h causes program to abort
           Product: binutils
           Version: 2.28 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

  Target Milestone: ---

Dear all,
Using AFLFast (, a fork of AFL, we found an
input causing different programs (addr2line, strings and size) to abort due to
an exception in peicode.h.

The bug was found on Ubuntu 14.04 64-bit & binutils was checked out from repository. Its commit is 
268ebe95201d2ebdcf68cad9dc67ff6d1e25be9e (Fri Nov 18 14:15:12 2016). We also
checked and confirmed the bug using the newest development version of binutils
& binutils 2.24. 

To reproduce:

> fd

addr2line -e fd


size fd


strings -d fd

Error message:

BFD (GNU Binutils) internal error, aborting at
../../bfd/peicode.h:896 in pe_ILF_build_a_bfd
