It's OSX 10.5.8 and GHC 6.12.1 as packaged in 
haskell-platform-2010.1.0.1-i386.dmg

It looks like that bug might only be fixed in 6.12.2? I dunno, Trac 
really needs some way of telling which non-HEAD version finally includes 
the fixes that close a ticket. I can never figure that out from reading 
the ticket...
