I experience this bug on the Raspberry Pi (with the current version of raspbian) using the eglfs platform (no window manager).
Description
To reproduce,
+Insert absolute mouse pointer device.
+Set QT_QPA_EVDEV_MOUSE_PARAMETERS=abs
+run analogclock -platform eglfs
(note: this is not specific to analogclock--it has happened with every program I have tried)
EXPECTED: analogclock runs with a mouse pointer showing
ACTUAL: application crashes (segfault)
Output from gdb (for one of my programs)
Program received signal SIGSEGV, Segmentation fault. 0xb64b0b80 in QScreen::virtualSiblings() const () from /opt/qt5_5/lib/libQt5Gui.so.5 (gdb) backtrace #0 0xb64b0b80 in QScreen::virtualSiblings() const () from /opt/qt5_5/lib/libQt5Gui.so.5 #1 0xb64b0e98 in QScreen::virtualGeometry() const () from /opt/qt5_5/lib/libQt5Gui.so.5 #2 0xb403c714 in ??
