"<interactive>: internal error: scavenge:"

[Serge D. Mechveliani]

Dear GHC team,

  ghc-6.0.1 
  installed from RPM on  Red Hat Linux release 7.3 (Valhalla)
  i-386 unknown

runs into the following bug after `making' of my large project and
when running the test
                      T_.test "log"  
from Interpreter:
  ...
  finds gs' = Groebner basis gs,
  tests the reduction of  fs by gs, gs' by gs, gs by gs',
  tests the transformation matrix fs -> gs
  --- RESULT:
  [True,<interactive>: internal error: scavenge:
  unimplemented/strange closure type 64 @ 0x4056c418
    Please report this as a bug to glasgow-haskell-bugs at haskell.org,
    or http://www.sourceforge.net/projects/ghc/

The same test compiled to  Main.main  and --make-ed to  a.out
runs correct.

The project is large, and the bug looks hard to locate.
The archive of the source to install is about   900 Kb.

I could send it to the GHC team on the subject of debugging GHC, 
if you tell me any appropriate personal address.
