Title:
double free in mir egl display when calling eglTerminate and
gbm_device_destroy
Status in Mir:
Incomplete
Status in mesa package in Ubuntu:
Fix Released
Status in mir package in Ubuntu:
Incomplete
Bug description:
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.
