39 * Test sproc_p.c
40 *
41 * The purpose of this test and the sproc_ch.c test is to test the shutdown
42 * of all the IRIX sprocs in a program when one of them dies due to an error.
43 *
44 * In this test, the parent sproc gets a segmentation fault and dies.
45 * The child sproc never stops on its own. You should use "ps" to see if
46 * the child sproc is killed after the parent dies.
