> If 3.9 shipped with these issues (assuming these are not false positive), it would be interesting to 1) know why the sanitizers didn’t catch it, and 2) add valgrind to the release qualification process (CC Hans).

Yes, I'd be interested to see some corroboration.  Note that the issue 
here is pretty specific: it only happens during optimized compile using 

This is all I did:

1. checkout LLVM/clang trunk

2. make sure clang in path is clang-3.9


cmake .. -GNinja -DCMAKE_BUILD_TYPE=RelWithDebInfo 


ninja check
