--- Comment #17 from Yury Gribov <y.gribov at samsung dot com> ---
This should be fully resolved once
https://github.com/llvm-mirror/compiler-rt/commit/d6535ea4c4d49078a93735b315b8518fb692a592
is merged into gcc trunk.

BTW it no longer reproduces on trunk because newer versions of libstdc++
silently call __asan_init from __cxa_atexit in some constructor:
