The fix in PR8750 solves the problem.
Verified with gcc3.3 and gcc3.4.

I think this may be related to PR8750 and (IMO, erroneously) closed
PR6810.
Could you try the patch to i386.c (ix86_expand_prologue ) that is in the
8750 audit trail. It may not be correct patch but at least it seems to
fix 8750 and *this PR on mingw32
