--- Comment #21 from dominik.stras...@onespin-solutions.com --- How can I help ? My goal is to run our entire regression test suite with STL debugging switched on as this is great for quality assurance. Having fought several problems, this now seems to be my final obstacle. After one year I now have a fix in a GCC release but unfortunately still no cigar. If you point me to sth. where I can look at I will happily try to contribute.
