Summary: Crash: Mesa checks for invalid pointer, then uses it
anyway.
Product: Mesa
Version: 7.9
Platform: All
OS/Version: All
Status: NEW
Severity: critical
Priority: medium
Component: Drivers/X11
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: gabrb...@gmail.com
Using Mixxx 1.9.0-beta on MeeGo (Mesa 7.9.1) I got a SEGFAULT here:
/* BEGIN: src/egl/drivers/dri2/egl_dri2.c:1548 */
geometry_reply = xcb_get_geometry_reply (dri2_dpy->conn,
geometry_cookie, &error);
if (geometry_reply == NULL || error != NULL) {
_eglError(EGL_BAD_ALLOC, "xcb_get_geometry");
free(error);
free(buffers_reply);
}
switch (geometry_reply->depth) {
/* END */
The pointer returned is checked for validity... but the function does not
return. The SEGFAULT occurs at the switch() statement.
