gdb backtrace

I am unable to compile Wine 1.1.1. 1.0 and 1.1.0 compile fine. I am getting the
following error:

../../tools/widl/widl -I. -I. -I../../include -I../../include  -D__WINESRC__
-D_RPCRT4_ -DCOM_NO_WINDOWS_H -DMSWMSG  -c -C epm_c.c epm.idl
make[2]: *** [epm_c.c] Segmentation fault

Interestingly, it crashes only if widl is compiled with -O2 (0,1 and 3 work). I
compiled widl with "-O2 -g" and ran it in gdb. I'm attaching the backtrace.
I'm using Gentoo and gcc version is "Gentoo 4.1.2 p1.0.2".

If you think this is compiler related, should I post a bug at Gentoo?
