--- Comment #2 from Reid Kleckner <rnk at google.com> ---
The fix caused a different crash while building Chromium for iOS:
https://build.chromium.org/p/chromium.fyi/builders/ClangToTiOS/builds/6190/steps/compile/logs/stdio

Assertion failed: (!isa<DILexicalBlockFile>(Scope) && "Don't expect Lexical
Block File!"), function addLocalScopeDieToLexicalScope, file
/b/build/slave/ClangToTiOS/build/src/third_party/llvm/lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp,
line 888.

We'll work on getting pre-processed source code, but in the meantime I would
like to revert to green.
