Yes, the package builds fine with -O2 and gives this segfault with -Os. So please revert this use of -Os, which is not the correct build option to use here according to policy. Cloning a copy of this bug to g++-4.1, since it does appear to be a bug in g++-4.1 to generate broken code in the -Os case. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
