It's yacc.  yacc-generated parsers are generally not reentrant, which
the completion code needs when `eval' (which runs the parser again) is
used.  Use bison to regenerate y.tab.[ch] and rebuild. (I used bison-1.28.)

It's partly my fault.  When I upgraded to FreeBSD 4.2 on my primary
development machine, I forgot to install bison, so the y.tab.[ch]
distributed with bash-2.05 are generated by byacc.

I'll probably have to put new y.tab.? files out on my ftp site soon.
