Very odd. You could try running under valgrind, and see if it gives you
more information about how the SIGSEGV happened.

I also just pushed a patch that does better error checking from the
return values of the argz_* functions; but I doubt that that is the
issue.

Is that the gnulib argz or a system-supplied argz ? You can check with
'nm gnulib/lib/.libs/libgnu.a | grep argz' - if that shows anything
you're using the gnulib argz (in which case it's strange we don't get a
line number for the SEGV)
