ghc 6.6 and 6.6.1 both go into infinite loops and eventually die with a stackfault when trying to compile the attached file with optimizations turned on. -- John Meacham - ⑆repetae.net⑆john⑈

Shouldn't it be 'newtype T v = T (V v)'? I can imagine ghc running in circles trying to derive instances for T. Regards, Arie -- Just follow the magic footprints.

Ah, yes. that was a typo and removing it fixes the problem. Cool. Though, still a minor bug in ghc I guess. John -- John Meacham - ⑆repetae.net⑆john⑈
