Thanks for reporting that.  I have verified that there is a bug here,,
in the GLR code of CVS Bison, if you have valgrind installed and then
run "./bootstrap; configure; make; make maintainer-check".  The
generated parser is using uninitialized data (I think it's supposed to
be a line number).

Paul, do you have "valgrind" installed <http://valgrind.org/>?
If so, can you please look into this?  Or perhaps you can figure
it out from this test run with valgrind:

$ cd tests
$ ./testsuite -v -d 87 PREPARSER='valgrind -q'
