Hi, I get the exact same thing with ghc-6.5.20060914. Weird.

RE: 6.6 strikes me again :)
Quite right; that's just as specified. The coverage condition is documented in the manual. (GHC 6.4 and Hugs are too liberal, and thereby risk divergence during type checking.)

UTF-8 decoding error
How can I convince ghc version 6.5.20060919 to accept latin1 characters in literals? I wish to keep source files (containing umlauts in strings) that can be compiled by either ghc-6.4.2 and ghc-6.6.

Re[2]: 6.6 strikes me again :)
Hello Simon, Wednesday, September 20, 2006, 7:35:39 PM, you wrote: Quite right; that's just as specified. The coverage condition is documented in the manual. (GHC 6.4 and Hugs are too liberal, and thereby risk divergence during type checking.) If you want this program to work, use -fallow-undecidable-instances let's look at the slightly modified program: class (Monad m) = MRef m r | r-m, m-r class (Monad m) = Stream m h | h-m newtype StringReader r = StringReader r instance (Monad m, MRef m r) = Stream m (StringReader r) coverage condition requires that monad type 'm' should occur in stream handle type 'StringReader r'. With MRef defined as bijective type function between m and r that is, in fact, true. may be compiler is just not smart enough to figure this? is using -fallow-undecidable-instances safe in this situation? what of MRef fundeps, r-m or m-r, is really necessary in this case - i think it is r-m ? -- Best regards, Bulatmailto:[EMAIL PROTECTED] ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
Update to Replacement GMP page
Hello all, I made another update to the notes on Replacing GMP, at http:// hackage.haskell.org/trac/ghc/wiki/ReplacingGMPNotes . It's pretty basic and you'd probably find it shabby, but comments, modifications appreciated. I am still in the throes of trying to *portably* beat GMP for speed and accuracy. (The portability problem comes in when I may no longer rely on Altivec/SSE/3DNow! support on other processors and need to optimise in pure C.) -Pete ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

Re: threadDelay not ending
* Rich Fought [EMAIL PROTECTED]: I've got some unit test code that forks off test processes using the 'system' function and then delays using 'threadDelay' to synchronize with the test process. This has worked fine until I upgraded to 6.4.2, now some of the 'threadDelay' calls never return - it's like they are stuck in limbo. You could build an RTS with debugging support to see what is going on.
