Re: `partition'
the function let ns = [1 .. 10^6] :: [Int] p = partition even ns in take 2 $ fst p computes too long in ghc-6.2.2-September-26 and needs several megabyte of stack. this has been noticed a few times, for example http://www.mail-archive.com/[EMAIL PROTECTED]/msg07508.html -- -- Johannes Waldmann, Tel/Fax: (0341) 3076 6479 / 6480 -- -- http://www.imn.htwk-leipzig.de/~waldmann/ - ___ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
ghc-5.04.2: panic! (the `impossible' happened, GHC version 5.04.2):
class Foo a where foo :: a - ()
data Bar = Bar { bar :: () }
instance Foo Bar where foo = bar
test :: Bar
test = undefined { foo = () }
the last line should be rejected, since there is no `foo' in `Bar'.

Re: GHC-2.08 on alpha, for a change...
Haven't properly investigated this myself yet, but just in case this looks familiar to anyone, I get the following, trying to build 2.08 on an alpha, with ghc-0.29. Unix assembler: gcc -o absCSyn/PprAbsC.o -c /usr/tmp/ghc10102.s as1: Internal: /usr/tmp/ghc10102.s, line 32: ../../../../../../src/usr/ccs/bin/as/as1util.p, line 460: idn sym_tab.alloc_len Fatal error in: /usr/lib/cmplrs/cc/as1 Segmentation fault yep, i was getting exactly the same behaviour, on alpha-dec-osf4.0. (already with ghc-2.05 i think). my "fix" was to generate PprAbsC.s, then assemble it on a alpha-dec-osf3.2 machine, and continue with that PprAbsC.o. regards, -- Johannes Waldmann Institut fur Informatik FSU D-07740 Jena Germany http://www5.informatik.uni-jena.de/~joe/ mailto:[EMAIL PROTECTED]
