I'm getting segmentation faults when using dynamically linked native
code in 64-bit OCaml 3.11 running
on Linux (Fedora 12 x64).

The .cmxs file loads fine.  There's a glue module that's "open"d in
the code for the dynamic module, and
linked against the main program.  The dynamic module calls functions
that modifies lists in the glue module;
the main code calls functions in the glue module that return the
current values of those lists.  The code that
modifies the lists seems to work OK, but the query functions reliably
give a crash.

I've written some small example programs with a similar structure, and
those work just fine.  In my real,
large program, which pulls in a lot of OCaml libraries, I get segfaults.

Any ideas what might be going wrong?  My code is not compiled with -nodynlink.
