Malcolm,
every non-trivial Haskell program compiled with nhc98 (current cvs) core
dumps on Solaris. The garbage collector seems to be the cause of the
fault. Small computations not requiring garbage collection work fine.
But take:
import List
plus x = x + 2
primes :: [Int]
primes = 2 : filter prime [3..]
prime :: Int -> Bool
prime n = not (any (`divides` n) (takeWhile (< n) [2..]))
divides :: Int -> Int -> Bool
divides n m = m `rem` n == 0
main = print (take 33 primes)
Then you observe:
myrtle$ Test +RTS -B
[2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,101,103,107,109,113,127,131<GC
1:Start>Segmentation Fault (core dumped)
Any idea?
With respect to building nhc98 (all). After a long time the process
stops with:

$
"$" is not a proper shell prompt. It does accept some input like "gmake
install" (without doing anything until interrupted), but it doesn't do
anything on input like "ls". I'm confused. In the end I only build "basic".
A minor point: When make tries to build the package haskell-src it calls
happy. Because I don't have happy installed this fails. No big problem,
because building continues. However, shouldn't configure test for happy,
warn about it and possibly exclude haskell-src from building...
Ciao,
Olaf
