   7  * Test sproc_p.c
   8  *
   9  * The purpose of this test and the sproc_ch.c test is to test the shutdown
  10  * of all the IRIX sprocs in a program when one of them dies due to an error.
  11  *
  12  * In this test, the parent sproc gets a segmentation fault and dies.
  13  * The child sproc never stops on its own.  You should use "ps" to see if
  14  * the child sproc is killed after the parent dies.
