Comment(by simonmar):
FYI, this first failed in the nightly build on 26 May. It was probably
tickled by this change:
{{{
commit 4063e1d8501b38b5ed8d620dcd8e27adee0e7091
Author: Simon Marlow <[email protected]>
Date: Wed May 25 13:06:05 2011 +0100
sizeExpr: multiply all the sizes by 10, except for primops. This
makes primops look cheap (but not free), and improves the Repro4.hs
example from #4978.
While I was making this change I accidentally discovered that
increasing the discount for scrutinised constructors was an
unambiguous win, so I did that too.
