Failed when building AOSP for angler with LLVM tip. This only fails with LLVM
tip, not with the prebuilts/clang in AOSP.

To reproduce the issue. Run the following command under the AOSP root dir.

/bin/bash -c "(true) && (mkdir -p

Quuxplusone commented 8 years ago

Please attach pre-processed source code that is normally generated when clang crashes, so that we can easily reproduce the issue.

Quuxplusone commented 8 years ago

Just tried the latest LLVM build and the compiler no longer crashes. Closing the bug.
