Bug ID: 20959
Summary: Firefox ASAN builds with clang-cl hang during startup
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: compiler-rt

Classification: Unclassified
We try to grab the same lock recursively, so the second time we hang with a
stack like this:

This is very similar to bug 20931. This is with MSVC2013, and ninja check-asan
passes on the clang-cl build from this revision.
