See runtime/ErrorHandling/SecondaryErrorTest.java, it is fed into VMError::controlled_crash().

That test crashes the VM first with one signal, then inside the error handler with a second, different, signal, to test that the second error signal was correctly unblocked or left unblocked. Otherwise, the VM would just disappear.
