/* This test program is for temporary testing only. It is not in the
   usual test suite (not in check_PROGRAMS from Makefile.am).
   In the 3.1 branch, it crashes before r9467, and r9467 fixes the crash
   (among other issues).
   In the trunk, it crashes, which is not expected with the current code.
