Re: Publisher double free on create
Frank Quinn <f.quinn@...>
Yeah that’s definitely an issue – happens in two places too and looks like there’s another issue in a section below it where it will be accessed after the free. I went ahead and raised https://github.com/OpenMAMA/OpenMAMA/issues/168 to track this - if you want to submit a patch you can work away, otherwise we’ll get it fixed when we get a chance.

Subject: [Openmama-dev] Publisher double free on create
I think I found an issue with publisher create. On the error paths in _createByIndex, the function mamaPublisherImpl_cleanup(impl) is called and then the impl is immediately freed after but mamaPublisherImpl_cleanup(impl) also calls free on the impl as well. mamaPublisherImpl_cleanup was introduce in the publisher event feature, I believe, and is used as a publisher destroy. Should the mamaPublisherImpl_cleanup function free the impl parameter or should create not free the impl on error paths?
