Even with -O1 -g ? With -g0 we prune BLOCKs, so the backtraces
don't work well.
Well with -O1 -g the backtrace works for this particular error. But
with -O2 -g, we trigger another error "asm not allowed in atomic
transaction", and no amount of %K fiddling will get me a backtrace.
But even so, it doesn't seem right to expect users to get a correct
error message only with -g, does it?
