The toolchain in question was created by me and I finally found time to
look at this.  I want to this PR reopened because I _can_ reproduce the
ICE with unmodified gcc:  gcc-4.4.5 (svn rev. 164871), binutils-2.20.51
(cvs 2010-10-03 08:20 GMT) and mingw-w64 crt and headers (release-1.0
branch, svn rev. 3696), all unmodified, I get this:

$ i686-w64-mingw32-g++ -v
Using built-in specs.
Target: i686-w64-mingw32
Configured with: ../gcc44-svn/configure --target=i686-w64-mingw32
--disable-multilib --enable-checking=release --prefix=/home/ozzie/cross_win32
--with-sysroot=/home/ozzie/cross_win32 --enable-languages=c,c++ --disable-nls
Thread model: win32
gcc version 4.4.5 (GCC) 

$ i686-w64-mingw32-g++ -fstack-check -O gen-duplicator-batch-files.cpp
gen-duplicator-batch-files.cpp: In function 'int main(int, char**)':
gen-duplicator-batch-files.cpp:610: internal compiler error: in print_reg, at
config/i386/i386.c:10678
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

This is on fedora10 x86_64-linux, the toolchain compiled using the
fedora-provided gcc-4.3.2.

The problem seems to be related to the -fstack-check switch, without it
there is no ICE.  Kai: How did you test this?
