Public bug reported:

In my standalone Xmir I do the following things:

/* Init code */
if (xmir_screen->gbm) /* NULL on !mesa */
    mir_connection_drm_set_gbm_device(xmir_screen->conn, xmir_screen->gbm);

xmir_screen->egl_display =
eglGetDisplay(mir_connection_get_egl_native_display(xmir_screen->conn));

/* Shutdown code */
    eglTerminate(xmir_screen->egl_display);

    if (xmir_screen->gbm)
        gbm_device_destroy(xmir_screen->gbm);

This works as expected when gbm is NULL, but I'm getting a double free in gbm_device_destroy with the eglTerminate.
Calling eglGetDisplay(xmir_screen->gbm) instead works as expected.
