Summary: Profiling crashes in heapCensus.

Initial Comment:

Fresh out of the box ghc-6.0.1 under RedHat release 9
crashes out (on the first program I tried it on, which
I'm hoping is just bad luck...), with the following:

[abf@4c60 CSP]$ ./mainruc +RTS -hc > runlog-ns3-hc
mainruc: internal error: heapCensus
    Please report this as a bug to
glasgow-haskell-bugs@xxxxxxxxxxx,
    or http://www.sourceforge.net/projects/ghc/

Other -h's seem to do much the same. OTOH, -p type
options seem to work fine.

Any debugging I can do at this end, or ought I to send
the whole kit and caboodle of the code that's causing this?

Cheers,
Alex.

I get the same error.  Will check again with 6.2 as you
said.  BTW, profiler is very impressive when it works :)

We've fixed a bug that could cause this crash in 6.2.  Please 
test again when 6.2 is released and let us know.
