Good that I'm not alone. I've just updated sources and the crash is still
here.  I've though that it might be usefull to post backtrace of this
crash, but gcc leave me w/o it since it just seems to finished with exit
code 01.

Is it possible to add some parameters to avoid gcc internal error handling
and to get proper backtrace?

Thanks,
