Release or debug build?

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

[dapperfu]

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.
