Thanks for the report!

Which operating system, compiler and build type are you using?

Ubuntu 18.04. Fails on both Ninja and GNUMake.

Release or debug build?

ps: Will not be around for almost one week. Gonna investigate after.

dapperfu commented 6 years ago

Release. Mostly following the build script.

And I'm in no rush.

It looks like I am able to reproduce the crash with LLVM_USE_SANITIZER set to Address. Will work on it as "soon" as I got time.
