Breaks the build:

/home/anthony/git/qemu/cpu-exec.c: In function ‘cpu_alpha_exec’:
/home/anthony/git/qemu/cpu-exec.c:204:15: error: variable ‘cpu’ might
be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
/home/anthony/git/qemu/cpu-exec.c:202:28: error: argument ‘env’ might
be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
cc1: all warnings being treated as errors

I think it's one of the warning patches from Stefan.  I cannot bisect
here.  My gcc info is below:
