ghci bug on initialization

Dear GHC team, 

The command 

ghci Models

generates the following error on my 64 bit intel dual core machine: 

[jve@localhost demo-devel]$ ghci Models
   ___         ___ _
  / _ \ /\  /\/ __(_)
 / /_\// /_/ / /  | |      GHC Interactive, version 6.4.1, for Haskell 98.
/ /_\\/ __  / /___| |      http://www.haskell.org/ghc/
\____/\/ /_/\____/|_|      Type :? for help.

Loading package base-1.0 ... linking ... done.
Compiling Models           ( Models.hs, interpreted )
ghc-6.4.1: internal error: mallocBytesRWX: failed to protect 0x0x165c050

    Please report this as a bug to glasgow-haskell-bugs@xxxxxxxxxxx,
    or http://www.sourceforge.net/projects/ghc/

The file Models.hs is in appendix. 

I am using ghc-6.4.1 on a Fedore Core 5 linux machine, 
running kernel 2.6.16-1.2080 (_FC5.x86_64). 

Regards, 

Jan
