Currently, one of my tests causes g++ segfault. --- main.cpp: In member function 'void BugContainer<ValueType>::bug() [with ValueType = Info]': main.cpp:35:1: internal compiler error: Segmentation fault --- It is always reproducible and tested on various configurations. I simplified code and made reduced testcase. gcc from the trunk rev 181801 date 20111129.
