So it turned out to be a stupid logic error in some weak ref management
code that I'd written. Although in the process of finding it I've
learnt a lot about Guile internals, so it wasn't a complete write-off of
my time.
Note to self: bugs can lie in wait for you for a long time...
Thanks to all who provided debugging tips -- I'll keep them in mind for
the future.
