Can we commit or close this PR? Trying to clear the PR queue. |
Background: Some allocators (tcmalloc) don't provide alignment guarantees that match clang's default expectations, which causes crashes when using clang compiled binary with such allocators. For example clang can produce movaps instructions to initialize newly allocated object - which would crash if result of ::operator new() is not 16 bytes aligned.
