I'm on OS X 10.7.5 with an Core i7. {{{ ghc : ade1ae97ed52c493ec415c1601dace39b64071dd testsuite : 743cab5865ae0b9820dadc33a692511e0e467b9b }}} I used `validate --slow`. Both 085e8145f63c8f42d8bc19cd3cff52b8cd5b6455 and 229323898b0809047b19b79c181085430cce9850 occur in my `git log` output. What info can I provide that would be more helpful? -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7684#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

The commit log in the patch mentioned that it might not be quite right for 64 bits. I don't have time to look at it right now, but perhaps someone else could fix it using the 32 bit patch as an example of what needs doing. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7684#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
