Thanks for the report; I'm adding gnulib, since that would be where the
fix (if any) should be made.  I need to make an m4 snapshot with a more
recent gnulib snapshot, to see if we've addressed this in the meantime.

Meanwhile, was configure still coming up with the correct answer, and just
printing bogus intermediate text, or was it failing to compile because of
the segv?  Perhaps attaching the complete config.log would be helpful.
