@b0rk So glad that #3 is immediately followed by #4.
My "good advice and maxims for programmers" from 199? has "Looking for a compiler bug is the strategy of LAST resort. LAST resort."
(Most of it is not actually good advice, but I think that bit holds up.)
@mjd @b0rk I once tracked a problem down to an actual factual compiler bug and I felt like I had won the lottery.
