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.
