See <http://gcc.gnu.org/bugs.html> for instructions. I'm wondering if that now could point more accurately to the point of failure? Just compiling the offending module with these options is not enough. I'd like to help debugging this, but I would need some hints on how to do this... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36037
