Well I think I've run into this problem...maybe. All but one of the tests pass, the one that doesn't is the timeLargeArray test, and it fails with this error yhc: superclassesI InfoUsed (Id 68) [(Type class,Ord,"Data.Ix",510:8-510:10)] Now my main question is how some PackedStrings can be reversed and others not when it looks like everything that uses PackedString imports it from SysDeps? The only exception I could find was compiler98/DotNet/Show.hs.
Hmmm that's interesting, did you change the compiler source code at all? You usually get those kind of errors because the compiler has ended up with a data structure that it wasn't expecting. Indeed all PackedStrings are imported from SysDeps, the problem is what happens after that. Sometimes they are used as string' = packString string and other times string' = packString (reverse string) There doesn't seem to be a lot of logic to the choices ... Cheers Tom
