See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccKa44NX.out file, please attach this to
your bugreport.


Additional Info:

I've reduced the problem according to
http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction. If one of the options
(-O2 -fnon-call-exceptions) is removed g++ does not fail anymore.
