     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.
