[cfe-dev] Clang :: Headers/cxx11.cpp failing

[Alp Toker]

Hi,

The test Headers/cxx11.cpp has been failing with a crash on
Release+Asserts builds since some time last week.

This doesn't show up on the build servers so is presumably OK in
Release-Asserts and Debug.

Trace attached. Will investigate if nobody steps up.

Alp.
