I would move this code to the done label below.

This doesn't seem to work unfortunately. If I move it, other tests start to fail. E.g. mypyc/test/test_run.py::TestRun::run-exceptions.test::testTryExcept with:
Traceback (most recent call last): (diff)
File "testutil.py", line 46, in assertRaises (diff)
yield (diff)
File "driver.py", line 42, in <module> (diff)
list(iter_exception()) (diff)
~~~~^^^^^^^^^^^^^^^^^^ (diff)
SystemError: error return without exception set (diff)
(diff)
During handling of the above exception, another exception occurred: (diff)
(diff)
Traceback (most recent call last): (diff)
File "driver.py", line 41, in <module> (diff)
with assertRaises(IndexError): (diff)
~~~~~~~~~~~~^^^^^^^^^^^^ (diff)
File "/Users/marc/Develop/01_temp/cpython/Lib/contextlib.py", line 162, in __exit__ (diff)
self.gen.throw(value) (diff)
~~~~~~~~~~~~~~^^^^^^^ (diff)
File "testutil.py", line 48, in assertRaises (diff)
assert type(e) is typ, f"{e!r} is not a {typ.__name__}" (diff)
^^^^^^^^^^^^^^ (diff)
AssertionError: SystemError('error return without exception set') is not a IndexError (diff)
So I think PyErr_Restore needs to happen earlier.

Hm, that's not making sense to me. Is the done label not getting hit in all cases?

It is, but some cleanup functions from mypyc seem to require that the exception is set properly.
Just the goto done; call is never used AFAICT.

Ok, that's a little messy. As long as they don't overwrite the exception, I guess it's fine.

That's the segfault exit code. |
