Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen

lz4-preprocessed source
Over at Mozilla's https://bugzilla.mozilla.org/show_bug.cgi?id=1390583 we are
trying to get Firefox cross-compiled for Windows using clang. This works thanks
to the efforts by Martin Storsjö and others if I compile Firefox 52 ESR (the
current long-term support version of Firefox). However, clang crashes during
compilation of the latest Mozilla code after lz4 got updated to version 1.8.0.
Here is the stack trace and bit of info and attached is the preprocessed source
and the associated run script.
