> vex amd64->IR: unhandled instruction bytes: 0xF 0xB 0x55 0x48 0F 0B is the official Intel undefined instruction, so V is correct to whack your app on the head with SIGILL at this point. The messages are admittedly confusing though. Why the program SIGILLd though, I don't know. One important question is: > UNKNOWN __pthread_sigmask is unsupported. This warning will not be > repeated. Does that also get reported for the XCode 3.x built version, or only w/ XCode 4?
