"make tags" segfaults

[Kai Großjohann]

For a while now, I've been getting segfaults during "make tags" from
the trunk.  Finally, I'm submitting a backtrace.  (I snarfed the
command line from the output of "make".)

Can anyone reproduce this?  (Just say "make tags".)  What else can I
do to help debug the problem?
