[Bug binutils/5279] New: objdump SEGFAULT in bfd_getl16

From: julia at fireeye dot com
Subject: [Bug binutils/5279] New: objdump SEGFAULT in bfd_getl16
Date: 7 Nov 2007 00:58:33 -0000

In certain Win32 PE (i386) EXE files (which might be packed), objdump segfaults
due to something in the PE headers. I can provide an example .EXE file to
reproduce this.

Reproduction: "objdump -x foo.exe"

Example backtrace:
        191009      0  RegQueryValueA   191009
        19101b      0  RegSetValueA     19101b
        19102b      0  RegSetValueExA   19102b
