Bug 11280

Hello,

After some investigation and help
(http://sourceware.org/ml/binutils/2010-02/msg00111.html), I've been able to
simplify this problem.

On Open Solaris 2009.06 i386, GCC 3.4.3 or GCC 4.3.2, with Binutils 2.20
configured as:

./configure --target='i686-pc-mingw32' --prefix='/export/home/tony/usr'

Windres segfaults when running this command (with pthread.h, version.rc, and
winver.h in .):

i686-pc-mingw32-windres --include-dir=. --preprocessor="gcc -E -xc -DRC_INVOKED"
version.rc version.o

The gdb output:

Starting program: /export/home/tony/usr/bin/i686-pc-mingw32-windres
--include-dir=. --preprocessor=gcc\ -E\ -xc\ -DRC_INVOKED version.rc version.o

Program received signal SIGSEGV, Segmentation fault.

Continuing.

Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.

If a codepage is specified via the -c option or by defining the macro CP_ACP in
binutils/winduni.h, the segfault no longer occurs.

I've attached the three files and also the core dump.

Please let me know if I can provide any further details.

Thanks,

Tony
