--- Comment #1 from Ian Lance Taylor <ian at airs dot com> ---
I think you know this, but to be clear, the test is supposed to dereference a
null pointer, and then it's supposed to recover from the run time panic.

The program should unwind the stack for the signal and call __go_check_defer
which should invoke the deferred function.  Can you find out where that process
is going awry?

If the recover* tests pass, then this test ought to pass, or at least it ought
not to fail in this way.
