Some questions:
 - Are you using the last version of binutils-2.22?
   The last version is bnu222br2.zip (2012-02-13).
 - Can I build gcc 4.7.0 and/or gcc 4.6.3 on my local
   WinXP mashine?  I would like to reproduce the issue.

In the worst case I could provide a new version of binutils 2.22
with some new environment variable that would allow to disable the
COFF extensions.  In that case you could chek if those changes are
really the culprit of the instability.
