The ill fated commit I made yesterday was a partial attempt to address some of the problems: basically, it boils down to DEBUG blocks that induce extra debugging output that the test framework doesn't know about.

You didn't used to get so many extra failures, but now GHC with -DDEBUG loves to say "constraint solver steps:<N>", so you basically can't test a compiler with -DDEBUG at all at the moment.

As Edward says, we should respect -dno-debug-output in these cases. There should probably be a variant of dumpTcRn that checks the flag. Cheers, Simon
