Bug#867974: libqt5gui5: new-delete-type-mismatch in QOpenGLContext destructor

[Sergey Sharybin <sergey.vfx@gmail.com>]

Package: libqt5gui5
Version: 5.7.1+dfsg-3+b1
Severity: normal

Dear Maintainer,

When building Qt5 application which uses QOpenGL classes with ASAN support there is
a new-delete-type-mismatch reported by the ASAN.

In order to reproduce the issue, it is enough to compile threadedqopenglwidget demo
application with -fsanitize=address, run the application, close all windows. See the
ASAN report in console after that.

This is likely the same exact issue as reported there:
