Repeated build failures in expr due to yyparse

Running a make -s -j5 buildworld;  cleaned the entire obj tree meanwhile.
Builds are running on a slightly older HEAD thought with an updated libc
and some headers.

I can reproduce this all the time.  Buildworld at this stage should be
self-contained, right?  So why is it failing?
