ghc -O .. `Segmentation fault'

[S.D.Mechveliani]

Dear  ghc-5.02-linux-i386-unknown,

You cannot compile with -O certain large project.
`Segmentation fault' appears after compiling half of it,
no matter how much  +RTS -M.. -RTS  is set.

The project uses multiparameter, overlapping and undecidable 
instances, and strict fields.

And Simon Marlow already has another bug archive on 
`Segmentation fault'.

I wonder whether these bugs are independent and whether the last 
archive is needed before the first bug is fixed.
Please, advise,
