[PATCH] D55120: [MemCpyOpt] memset->memcpy forwarding with undef tail

[Nico Weber via Phabricator via llvm-commits]

thakis added a comment.

Heads-up that this causes crashes during static initialization in one binary in the chrome/win build, https://bugs.chromium.org/p/chromium/issues/detail?id=913423 I don't have a reduced repro yet, but my feeling so far is that this will be a compiler bug, not a code bug. (Nothing to do here yet until I have a repro.)
