New issue 3772 by [email protected]: V8 is not -fsanitize=enum clean
https://code.google.com/p/v8/issues/detail?id=3772
Two issues detected during mksnapshot:
* AllocationSpace and ObjectSpace are out of sync, leading to
out-of-range enums during chunk (de-)allocation.
* A visitor ID (specialization) in GetVisitorIdForSize is out-of-range.
It's highly unclear if this really hurts us, but at least it gives me a
very uneasy feeling... ;-)
Easily reproducable with Chrome's clang:
CXX="$MY_CHROMIUM_CHECKOUT/src/third_party/llvm-build/Release+Asserts/bin/clang++
-fsanitize=enum"
LINK="$CXX" make -C ~/v8 -j32 x64.debug.check
