--- Comment #25 from Kostya Serebryany <kcc at gcc dot gnu.org> ---
Even with this workaround asan is almost unusable with the buggy kernel.
I suspect that when a process has too many mappings it gets too slow.
The machine where we have our clang-asan bootstrap gets very slow and
unreliable.
We have reverted the kernel on that bot
(http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-bootstrap/)
and reverted the above workaround in llvm trunk.

The kernel fix went into Linus's tree for 3.14 last week,
and was tagged for stable backport. Nothing else we could do here.
