Ticket #5151: test-process-exited-raises.2.diff

File test-process-exited-raises.2.diff, 1.2 KB (added by hodgestar, 4 years ago)

Less broken version of the simple test that raises during processExited and explodes the reactor. Fails (and explodes all later tests) without exarkun's patch. Passes with it.
