/**
 * This test checks the result if in CK_NOFORK
 * mode a unit test fails but a checked teardown
 * runs after the failed test.
 *
 * Previously, the failure would be reported as:
 *
 * 0%: Checks: 1, Failures: 1, Errors: 0
 * (null):-1:S:tc:will_fail:0: Assertion '0' failed
 *
 * The reason why this happens is this: the end of the
 * message sequence coming down the pipe is CK_MSG_LOC
 * (location of failing test), CK_MSG_FAIL, CK_MSG_CTX
 * (TEARDOWN). It is this final message that confuses
 * things, because rcvmsg_update_ctx() updates
 * rmsg->lastctx (which likely is the right thing for it
 * to do), which is the ctx value used by the first 'if'
 * body in construct_test_result() in its call to
 * tr_set_loc_by_ctx().
 *
 * After the fix, the test failure should be reported
 * as:
 *
 * 0%: Checks: 1, Failures: 1, Errors: 0
 * check_nofork_teardown.c:33:F:tc:will_fail:0: Assertion '0' failed
