Considering that H.J. is working towards a --with-build-config=bootstrap-asan

mulitple instances of ASAN:SIGSEGV.

The majority of the libstdc+++-v3 testsuite failures seen with

I don't see the g++.dg/eh/cond1.C execution failures on x86_64 Fedora 15 so
this may well be darwin specific. In gdb, on x86_64 darwin12

This problem doesn't occur with x86_64 Fedora 15 built with --disable-tls.
Also, using llvm 3.2's clang++ on x86_64-apple-darwin12, I can compile
