Hm, I tried to reproduce this as well, but unsuccessfully. From the crash report: EXC_I386_GPFLT means we’re dereferencing a non-canonical pointer, in this case “0x00486000000025df”. This happens at wrap_OSSpinLockLock+17, which is just after the prologue and just after calling cur_thread(). So I’d say it happens when we’re dereferencing the pointer returned by cur_thread(). On OS X, we’re
