It turned out that, indeed, it was a very simple error. I inadvertently
included a return statement in the brackets for one of my productions. This
causes bison to halt.

That doesn't necessarily mean that the scanner is OK; it could be that
there is a bug in the scanner that is tickled by Bison 1.75.
Have you tried it with Bison 1.875? Or Bison 1.875a?
ftp://alpha.gnu.org/gnu/bison/bison-1.875a.tar.gz
If that doesn't fix the problem for you, please post more details
about your scanner and parser, as we can't help much from what you
wrote.
