I would guess it is related to GC or bad memory allocation (in case of C
code).
As far as I remember, OCaml GC is using usual libc malloc and free, so
you could activate libc checks to help find the bug (see mcheck(), there
is also an environment variable I don't remember). You could also take a
look at libefence.
Other things that might help is to zeroing data structures before
releasing them to free(). Sometimes, you reuse a datastructure that is
has been freed.
To make the port, what have you modified? Only Caml code or also C code?
My .2 euros,
Yours,
