Thanks for the report.

I pushed the following patch to branch-2.4.3 and something similar to 
branch-2.5 and master.

Would you please check that the problem is fixed?  Either I can roll a 
test release tarball for you to try, or you can checkout branch-2.4.3 from 
our git repo at git://git.sv.gnu.org/bison.git and then bootstrap.  
Either way, you'd then run the usual ./configure, make, and make check. 
Let me know what is easiest for you.  Thanks.
