Did you recompile/relink these glue functions when moving up to the new
version? Are they built with debugging enabled?

The trace is *really* suspicious given what you say here. I'm inclined
to think that what is really happening is that something is jumping to
never-never land (via a clobbered function pointer or overwriting a
return address on the stack) and it just happens to end up in FileRead.
Unfortunately that guess doesn't provide much help for debugging it :-(
