> Due to a bug in LLVM's build system, building LLVM a second time fails when building runtimes (complaining that clang fails to build a simple test program). A workaround is to build it yet again (it works each other time, i.e. the 1st, 3rd, 5th etc. time).

I'm incredibly curious what this bug might be!

Unrelated to this issue but I've had a race condition with Automake which while run oin 2-4 threads occured exactly every 2nd run. With -j48 it was obvious it's a race condition. No idea how cache invalidation works in the automake stack, but that must have caused it to fail exactly 50% of the time.

I just yesterday read about obfuscated Trojan quines in compilers, and a good test being building the compiler twice and it being the same, and now I hear this.

Spooked me for a sec xD
