Subject: [Bug binutils/5278] New: objdump SEGFAULT in _bfd_pe_print_private_bfd_data_common
Date: 7 Nov 2007 00:51:07 -0000

Several Win32 PE files, which appear to be UPX compressed, with broken/tweeked
headers, cause SEGFAULTs (sig 11) when run as "objdump -x foo.exe"

Example backtrace:
The Export Tables (interpreted UPX1 section contents)

Export Flags                    eb34e215
Time/Date stamp                 ebd57074
Major/Minor                     -21660/-29690
