Summary: abnormal termination(global variable __m128i　type)

Initial Comment:
When I declare __m128i type by global variable and use it, it is terminated
abnormally.
There does not seem to be no problem when I compile it in g++.

Environment:
gcc 4.3.0(20080305) alpha-testing
binutils-2.19
w32api-3.13
mingwrt-3.15.2
Windows XP Home Edition SP3(Japanese)

Thank you for commenting.

I add a test code.
Please compile it with the following option.
gcc -o test-sse2.exe test-sse2.c -msse2
gcc -o test-sse2b.exe test-sse2b.c -msse2

In addition, this does not reappear in the cross compilation environment
(Debian lenny). 
It is the problem that it met with in MinGW on Windows.

Message:
Can you please provide a minimal, but complete and self-contained test
case, which illustrates this problem, and includes detailed instructions on
how to reproduce it?  Without such detail, there really isn't much we can
do to progress this.  (If, as you seem to have determined, this actually is
a binutils issue, you will need to provide such information anyway, when we
direct you to submit a report to the binutils project).

Additionally, can you please be more specific as to which of the binutils
versions you have tested exhibit this issue, and which behave as expected,
for this isn't at all clear from your previous comments?

FWIW, using *our* cross-compiler build on Ubuntu-8.04, the code you *have*
provided as a test case doesn't even compile for me:

  $ mingw32-gcc --version
  mingw32-gcc (GCC) 3.4.5 (mingw-vista special r2)
  Copyright (C) 2004 Free Software Foundation, Inc.
  [...]

  $ mingw32-ld --version
  GNU ld (GNU Binutils) 2.19
  Copyright 2007 Free Software Foundation, Inc.
  [...]

  $ mingw32-gcc test-sse2.c
  test-sse2.c:3: error: syntax error before "dummy"
  test-sse2.c:3: warning: data definition has no type or storage class

In version 2.18.50-20071123 - 2.19 of binutils, the same problem seems to
happen.

The package which I confirmed is as follows.
binutils-2.19-mingw32-bin.tar.gz
binutils-2.18.50-20080109-2.tar.gz
binutils-2.18.50-20080109.tar.gz

Message:
This problem happened in gcc-3.4.5.
It seems to be a problem of binutils not gcc.
This seems to be a problem of GNU ld (GNU Binutils) 2.19
When it was GNU ld version 2.17.50 20060824, there was not a problem.
