Hi,
This is for your information only, I am not asking for any help. (I
compiled ghc-5.00 with the standard procedure and didn't encounter a
single caugh -- quite impressive!)
With operational and `make install'ed ghc-5.00 and ghci-5.00, I
changed the optimization flags:
======================================================================
0|40 fis@pannu (/l/fis/build/ghc-5.00/mk) $ diff config.mk{-orig,}
160c160
< GhcHcOpts=-O -Rghc-timing
---
> GhcHcOpts=-H180M -O2 -fvia-C -O2-for-C -funbox-strict-fields -fignore-asserts
>-funfolding-update-in-place -funfolding-use-threshold24 -Rghc-timing
======================================================================
Then I did `make clean && make', and this morning I found:
======================================================================

Please report it as a compiler bug to [EMAIL PROTECTED],
or http://sourceforge.net/projects/ghc/.

Please ask if you need more information.
