Hmm, I'd suggest to try the latest version from CVS if you can do
that.  There might already be some fixes in there.

Other than that, assuming that your debugger gives accurate
information, you would need to pin down exactly why the process
receives the signal.  What is the value of `x' and why doesn't
SCM_STRUCT_VTABLE_DATA succeed.  After we know that, we can try to
find out what has gone wrong.  The `structs' of Guile are hairy...
