[PATCH 0/4] Fix crash when generating IELR

Hi Dwight,

Thanks for the report.  I was very afraid it would be super hard to
track and fix (I don't know much about the IELR part of Bison), but it
turned out to be actually quite simple (the fix is the last commit,
the shortest one).  And it's quite amazing that you are the first one
to face this problem!

Could you please try the fix to confirm it on your real case?  It's
in:

I would like to use your (reduced) grammar as a test case, but it is
not trivial, so I would need you to sign the FSF disclaimers.  Would
you agree with that?

About the grammar itself: it seems to be generated, isn't it?  How big
is it?  Can you tell us more about how it is built?  Is it available
somewhere?

Thanks in advance.

Cheers!
