Crash while repetitive change of window

[renoust]

Hard to trigger on purpose, but a recurring crash.
I am currently curating a dataset using Tulip visualization and frequently changing window (mostly Ms. Excel) using option+tab. The frequent change and repetitive change occasionally results in a crash of Tulip (stack trace pasted below). Note that the graph contains a lot of node textures.

(The version of Tulip is self compiled from 5.2 / mac / clang / x82_64)

(I tried to reproduce it on purpose but it is difficult, here are some other clues that may help:

• the instance of Tulip (not the perspective because this is the one that crashed) was open for quite a while, I had to quit and relaunch it because no new graph perspective was loading my graph anymore at some point.
• I was regularly suppressing couples nodes between my quick opt+tab manipulations)

Anyways, I wrote this message to share the stack trace should it help.

Seems to be a qt/MacOSX specific problem.
As you can see in the stack trace of the crash, Tulip is not involved (no tlp:: function in the stack).
Since the problem occured in your own build of Tulip, I suggest you to try to reproduce it in using the downloadable build of Tulip 5.2.

I see, thanks a lot! I just opened the problem to communicate the stack trace, I think we may close it for now. Should I get the issue again with the official bundle, I may reopen the issue. -- Benjamin

Let me know if it works or not with the official bundle.
