Summary: ghci failure using .ghci to define macro

Initial Comment:

Windows 2000

I have defined a macro that I adore (it runs quick check 
on all properties within a file).  Manually, when I run 
ghci, I type the following to set up that macro:

  :load OdmQuickCheck
  :def checkAll checkAll

I then proceed to the meat of my GHCI session, knowing 
I can now type something like:

  :checkAll IntersectionTest

and receive immediate feedback as to whether my 
latest "optimization" actually broke the algorithm.

Okay.  That's all background.

So, I put the two lines above into a .gchi file:

  :load OdmQuickCheck
  :def checkAll checkAll

Then, I invoked ghci with a different module from the 
command line:

  ghci IntersectionTest

I'm hoping, then, to be able to directly use the macro:

  :checkAll IntersectionTest

After all the tests have run, something "bad" happens, 
and I see the following:

C:\ghc\GHC-50~1.3\bin\ghc.exe: fatal error: 
scavenge_stack: weird activation record found on 
stack: 0

I think this may have something to do with the 
compiled/interpreted state of the modules involved, and 
whether the module itself imports OdmQuickCheck, but 
I've been unable to so far to isolate these dependencies.

I'm hoping that you'll know right off... that it has 
something to do with the :def command not fully binding 
the macro... but if you have no idea, let me know and I 
can provide more data, sample code, more data points, 
etc.  Don't hesitate to let me know what you need.

Thanks!

This is a new one on me.  Could you provide enough 
instructions to reproduce the problem please?
