[Mac] SFContext::~SFContext crashes due to failed assertion
« on: March 22, 2015, 12:29:40 pm »
Hi.

When having loaded resources in a thread on OS X, the application crashes on exit due to a failed assertion in AutoReleasePoolWrapper.

Minimal sample:
(click to show/hide)

Stacktrace:
(click to show/hide)

PS: I'm using current master version from github.

This is a known issue. See workaround here: https://github.com/SFML/SFML/issues/790

Sounds like a very odd workaround, but I will give it a try. Good to see that it is already known. Thanks.

This workaround did work some time ago, but now I get that error again.

Just to be sure, you mean that the SSCCE with the mentioned workaround from https://github.com/SFML/SFML/issues/790 no longer work, or that the workaround no longer work with your minimal example from above, or both no longer work at all?

The SSCCE doesn't cover my use-case (it is drawing in a separate thread whereas I draw in the main thread and just load resources in another), so I didn't try it.
My minimal sample from above though crashes even when using the workaround from issue 790 (calling sf::Shader::isAvailable()) as first line (or just about anywhere) in the main() function.

Okay, thanks for the precisions. I really need to address this issue but I don't know when I'll have some time...  :-\
