I'm getting a crash when running the rend3 examples in --release mode with lto=thin and using LLD. (edit: Happens in both dev builds and release builds when using thinLTO)
Rend3 repo: https://github.com/BVE-Reborn/rend3
Tested commit: 4d107951a3ba62a58a7be1849eb670d05f269e20
I expected to see this happen: It doesn't crash instantly when attempting to run it.
Instead, this happened: It crashes instantly when attempting to run the examples.

There's no backtrace, but running it in windbg it just loops these errors:
