1397	GHC blows up while compiling Language.Haskell.TH.Syntax with -O2	simonmar		"When compiling Language.Haskell.TH.Syntax, GHC grows to over 2Gb here on x86-64.  This is a stage1 compiler, built by GHC 6.6.1.  This bug has apparently been introduced recently, because we're seeing out-of-memory errors where we weren't previously, but I haven't been able to track down when it was introduced yet.

Looking at the -v2 output, the Core size jumps first for FloatInward (3x), and then for LiberateCase (10x).  After LiberateCase, GHC keeps on growing - perhaps there's also a space leak exacerbating the problem."	bug	closed	high	6.8.1	Compiler	6.7	fixed			Unknown/Multiple	Unknown/Multiple		Unknown
