We know about the threaded RTS bugs on Sparc, and 6.4.3 won't be released without a fix for this. I'm actually quite glad that we've forced this into the open with 6.4.2, otherwise the bug would probably have remained dormant, affecting only those who used -threaded on Sparc.

Solaris x86 has similar bugs with the RTS (like mentioned in previous posts). A summary: 6.4 branch from cvs changed the occurrence a bit - it is harder to reproduce it - but possible - and now it segfaults (before - 6.4.2 - it hanged). To try a debug enabled -threaded version of ghc and follow http://hackage.haskell.org/trac/ghc/wiki/DebuggingGhcCrashes is on my TODO list. Regards Georg Sauthoff
