In mesa/src/gallium/auxiliary/hud/hud_context.c we find the following code case ',': env++; y += height + hud->font.glyph_height * (pane->num_graphs + 2); if (pane && pane->num_graphs) { LIST_ADDTAIL(&pane->head, &hud->pane_list); pane = NULL; } break; pane is checked for being NULL. So obviously we expect NULL as possible value. But we use pane->num_graphs before the check. This is possibly a NULL-pointer dereference. The problem was indicated by cppcheck http://cppcheck.sourceforge.net/ Best regards Heinrich Schuchardt
