Is this branch contain the same changes from #341? I'm reading it from my phone so hard to tell. |

To answer my own question, it is. I'm testing this now but its looking good! |

The return within the try statement can get tricky.

I don't really see the issue here.

To elaborate, the link that you posted warns against relying on try {} finally {} as the finally may not be executed, but in such a case the problem has either exited already or is in the process of doing so, so we don't have to worry about dereferencing the Python resources anyhow.

It was more of a caveat, return statements within try statements confuse me at times.

Is there a call to Cleanup missing?

That part is not used anymore as there is only a single ModuleDef instance that is kept for the whole run time, I'll remove it.

Cool, after it's removed I'm ok merging it. This fixes the issue for Python2.7, but it still occassionally fails on Python3 but it seems to be due to a different section of code

Yeah, I noticed that too, I'll try to reproduce the issue, for me it happens (after these patches) not anymore on Shutdown but only on Initialize.
Keeping the PyMethodDef around like the documentation (https://docs.python.org/3.6/c-api/module.html#c.PyModuleDef) suggests fixes issue pythonnet#262.

Cool, will merge after CI completes. Thanks! |
What does this implement/fix? Explain your changes.
Fixes issue #262 by countering two memory corruption issues.
Does this close any currently open issues?
#262.
Any other comments?
Is currently based on my other PR, but doesn't strictly need it, I could rebase.
