So it's either a problem in the way I use Boehm's finalizer registration
(in particular I pass a function pointer where a void* is expected!),
or a problem in Boehm's finalization, or a problem in the implementation
of `dispose'. I would favor the first alternative considering that what
you say below.

OK.
