OK, but why is yylex being calling more than four times?  It's called
only four times on my host.  So there is some _other_ bug that the
yylex issue is a symptom of.

The problem is, how do we isolate that bug?  One way to do it
is to use GDB to trace through the same test on both a working
host (e.g., Debian stable) and your non-working one, and see
where the two behaviors start to diverge.
