minimal working example
I've tried to compile wpa_supplicant with clang 2.8. I believe this worked with
clang 2.7, it certainly does with gcc 4.4.4.
While compiling src/crypto/sha256.c, clang appears to hang (or take insanely
long with 100% cpu load)
This does not happen with gcc 4.4.4, or when optimization is turned of (-O1
hangs, -O0 does not). I believe it also didn't happen with clang 2.7 although
I'm not sure.
I've attached a minimal working example.
I'm on amd64 linux 2.6.35.6.
