GLibtest_trap_assert_stderr

Assert that the stderr output of the last test subprocess matches serrpattern.

See g_test_trap_subprocess().

This is sometimes used to test situations that are formally considered to be undefined behaviour, like code that hits a g_assert() or g_error(). In these situations you should skip the entire test, including the call to g_test_trap_subprocess(), unless g_test_undefined() returns true to indicate that undefined behaviour may be tested.
