   1 * Culled from 970528-1.f in Burley's g77 test suite.  Copyright
   2 * status not clear.  Feel free to chop down if the bug is still
   3 * reproducible (see end of test case for how bug shows up in gdb
   4 * run of f771).  No particular reason it should be a noncompile
   5 * case, other than that I didn't want to spend time "fixing" it
   6 * to compile cleanly (with -O0, which works) while making sure the
   7 * ICE remained reproducible.  -- burley 1999-08-26
