UnrealEditor 4.15 Hangs when modal dialog appears on Mac OS X

Hi,

I’m experiencing intermittent editor freezes due to a multithreaded safe retain count release. I have reported this problem with a different use case which ended up with the same result before. It was related to device connection and disconnection event firing. Now, it’s just happening when modal dialog opens, not always, but sometimes, definitely happens, though, regardless. I’m killing and restarting the editor every 5 minutes. This is a part of complex code that probably requires a careful attention. I wouldn’t fix and commit the code although I will fix and use the editor for myself though. I think this needs to be taken of and reviewed by Epic engineers. Thanks.

I attaching the process sample result to show where the code is entering infinite loop.

Hi ,

Does this happen only in a custom project or can you reproduce this working in a blank, blueprint or C++ template? If you are able to reproduce this in a blank template, can you provide repro steps in order for us to reproduce the issue on our end? Lastly, please provide your system specs.

Providing this information will help us address the problem as efficiently as possible.

Thanks,
