  Let me jump in here with a guess.

  Don't be offended Alexei, and I might easily be wrong, but I think
this problem is that you don't know COFF format well enough.

  It is possible in COFF format to have unused space within the
COFF file.  If a file with unused space is generated then that
unused space will have whatever bytes were left over in RAM in
some buffer the compiler allocated but incompletely used.

  The bug you reported, perfectly fits what you would see if
you use a COFF dumper that tries to interpret the entire file
on a file that contains garbage in unused spaces.

  The question is easy to resolve.  Just use someone else's
COFF dumper on the same two files.  If doesn't see the same
difference then the difference is in an unused part of the
file.
