Alas attempts at making such an input have met with miserable failure.

Whatever the bug is, it seems highly dependent on the environment.  I
got to config.status.cutdown below which provokes the segv under

        env - PATH=/bin:/usr/bin sh config.status.cutdown

But the full config.status run that way seems to work (in other
circumstances it doesn't).  In each case though the offending line is

  CONFIG_LINKS=${CONFIG_LINKS="$config_links"}

The suggested variant from the manual seems to work

  test "${CONFIG_LINKS+set}" = set || CONFIG_LINKS=$config_links

But the problem looks too subtle to confidently say that's a definite
fix.
