Paul, I looked into your November 14 Bison bug report
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001901.html>,
and I think I've fixed that error-location bug in LALR(1) parsers; but
GLR parsers still fail the (revised) test case. If you have the time,
can you please look into the problem? The fix I just installed is in
<http://mail.gnu.org/pipermail/bison-patches/2002-December/001425.html>.
You should be able to reproduce GLR problem by checking out the latest
CVS version of Bison, uncommenting the last line of tests/actions.at,
and doing a "make check".
There are still some other bugs in this area, both for locations of
rules whose right-hand sides are empty, and also perhaps for freeing
storage associated with locations. But one bug at a time....
