Alex, have you seen something similar to this stack?
Just by looking at it, I don't see anything that helps my analyze this.
Could be a problem unrelated to asan (e.g. an uninitialized memory that behaves differently
under asan).
Unless Alex knows something about this stack trace we'll need a reproducer.

I haven't seen anything similar.

Nick, can you please re-run the app with ASAN_OPTIONS=verbosity=2 and attach the log?
You can also try to set ASAN_OPTIONS=replace_cfallocator=0 to see if it helps to work
around the problem.
I guess we'll still need the repro.

Ping. Is this still reproducible?

Will work on getting you a simpler testcase.

I've fixed a bug in the replace_cfallocator flag yesterday, which could change the output
of asan-no-replace-cfallocator. Could you please try with the latest Clang?
Overall I'd love to reproduce this locally somehow, because I still do not have an
idea what's going on.

I don't build clang, I get it from Apple. ;-)
What revision should I at least checkout?

I believe the Clang shipped by Apple doesn't fully support ASan at the moment.
Please take some trunk revision, e.g. 166410

I didn't even think of that.. They also shipped on that simply crashes on lambda's for
a while, haha. I'll check that revision, thanks!

I can't reproduce it in clang version 3.2 (trunk 166676), so I think you can close this
bug. Seems like Apple shipped a version without (complete) asan support.
