Erreur de segmentation

thanks, any chance you could build score with debug symbols? (-DCMAKE_BUILD_TYPE=Debug and no stripping). Here on ArchLinux the window correctly closes when deleting the device from the device explorer :|

Here's what GDB prints (I think it's the code at version v3.1.11).

The code in WindowDevice.cpp doesn't seem to have changed since v3.1.11 so far. The faulty line is

if(const auto& w = m_screen->window())

and gdb does not seem to be able to print the value of m_screen, which is consistent with something going wrong with the pointer.

In case that's useful, on Linux I'm running the "nouveau" video driver, and my window manager is Openbox.

Given the fact that the issue also happens on MacOS, I doubt the problem is with the video driver or the window manager, but you never know.

this should have been fixed since 3.1.12, can you check on the latest release ? https://github.com/ossia/score/releases/v3.1.13
