00040  *
00041  * The purpose of this test and the sproc_ch.c test is to test the shutdown
00042  * of all the IRIX sprocs in a program when one of them dies due to an error.
00043  *
00044  * In this test, the parent sproc gets a segmentation fault and dies.
00045  * The child sproc never stops on its own.  You should use "ps" to see if
00046  * the child sproc is killed after the parent dies.
