I wish I could, but I am tied in using a much larger set of tools with
many other people running Solaris 2.5.1, 2.7, and 2.8. So far we have
not found any problems running those 2.5.1 compiled tools on any of
our systems. But, as you said, there is always a chance and I will
keep it in mind.

Yes

I ran into the problem using 5.02.1 binaries, upgrading to 5.02.2 did
not help.

I grabed the failing invocation and added +RTS -H10m, and then -H20m.
All invocations fail the same way.

Using gdb, I found that the core was from a perl invocation. Using -v3
I found ghc-split to dump core.
:
*** Splitter
/home/dorr/func/haskell/sources/ghc-5.02.2/ghc/driver/split/ghc-split
/tmp/ghc21821.split_s /tmp/ghc21821.split
/tmp/ghc21821.split
Bus Error - core dumped

How can I preserve the tmp files, so I can debug the perl run? I don't
know anything about what split is supposed to achieve. Where should
I read up on this?
