Hi Simon,
I'll set up ssh access to a dual processor FreeBSD box. It should be
ready by later today (I'll send a note).
Best,
Greg

Just a quick note to say thanks for all the offers of help on
6.4.3 - it's very encouraging to see so many people willing to
offer their time and machines.
The state of play so far:
On FreeBSD, reports suggest that there's are one or possibly two
problems exposed by the threaded RTS. The timeout program in the
testsuite sometimes hangs, and GHC itself may hang when linked
against the threaded RTS. This looks like a tricky one, so I'm
going to try to look into it myself. I've installed FreeBSD 6.1
on an old laptop and I'm currently building 6.4.2 on it.
On MacOS X / PPC, we have a crashing stage2 when linked against
the threaded RTS. Gregory Wright is trying to reproduce the
problem on a smaller scale (with something other than GHC).
The "timeout hanging" problem apparently happens on MacOS X/Intel
too (according to Joel Reymont). If I find the cause on FreeBSD,
we can test the fix on MacOS X/Intel.
I have an update on FreeBSD. I built the CVS 6.4 branch on a fresh
install of
FreeBSD, and ran the testsuite:
OVERALL SUMMARY for test run started at Thu 3 Aug 2006 09:42:30 BST
1365 total tests, which gave rise to
4157 test cases, of which
0 caused framework failures
583 were skipped

46 expected failures

Some of those failures are probably due to running out of memory on
this laptop
(which only has 128M + 256M swap, I should have given it more
swap). But I
don't see any evidence of hanging timeout processes and stage2
apparently works
fine.
That means the problem only shows up on a dual proc/dual core
(Gregory reported
seeing this on a dual proc build of FreeBSD). Greg - can you give
me SSH access
to your box, and I'll take a look?
Cheers,
Simon
