Error by llvm MemorySanitizer
Currently the CI fails with a MemorySanitizer error when compiled with clang.
From IRC:
based on the error message and 'quelle: internet' it seems that it's a brokeness in llvm. I think it is triggered by librhash trying to check if it has optimised code it can load for the given platform. the problem with false positives however is that if you blindly ignore them maybe one day a true positive is around to hit you from behind.
I'm not sure if skipping that step is the right thing. However it clearly seems to be an option to me at this point.
Generally libigloo does a lot of low level memory management. Hence it's good to have those extra checks.
