I can't reproduce this. On my machine confirmation dialog appears as a result of ImGui::OpenPopupEx and there is no crash.

Can you build ImRAD with debug info (use provided release-linux script, change cmake invocation to DCMAKE_BUILD_TYPE=Debug) then run it from gdb and post the exact backtrace of the crash?

Okay seems I finally found it. The required action is Alt+F4 (app close) not Ctrl+F4 (tab close). Fixed.
