Seems to be. I can reproduce a massive compile-time difference (up to a
50% increase) between 108479 and 108480, but I'm having trouble figure
out where exactly that time goes.
Joern, please revert the patch for now. I'll be away for three weeks;
if no one else works with you on this in the meantime I'll help once I'm
back.
