Summary: Assertion failed in GC.c

Initial Comment:
Instructions:

1. Download the attached archive.
2. tar xzf gens.tar.gz
3. cd gens
4. make
5. make Env/If.so
6. ./gens - <tests

The message I'm getting is:

ASSERTION FAILED: file GC.c, line 1722

When I compile without -debug option, there's a
segfault with no error report. If I do +RTS -G1 -RTS,
the tests keep running longer, but they still crash in
the end.

There's another weird thing, probably unrelated.

./gens-prof +RTS -xc -RTS - <tests

outputs stack frames ending with readFile function
call, like it was throwing an exception and catching it
immediately. After the readFile call, execution
proceeds normally.

There's an error in the code I attached. File GensSystem.hs,
line 150:
   sizeOf fi = 8
should be 
   sizeOf fi = 16

But even with this fix I get the same GC error. I suppose I
could be doing something wrong with the Storable Interface,
but I can't see anything.
