Hi, Running on Ubuntu's upcoming Intrepid release I experienced X crashes when I quit emacsclient. The gdb log shows XrmDestroyDatabase() is the failing line. Looking at src/xterm.c lines around about 10514: #ifndef USE_X_TOOLKIT /* I'm told Xt does this itself. */ #ifndef AIX /* On AIX, XCloseDisplay calls this. */ XrmDestroyDatabase (dpyinfo->xrdb); #endif #endif So this code assumes only on AIX XCloseDisplay itself calls XrmDestroyDatabase but this doesn't seem to be the case, looking at libX11 1.1.4 source code, src/OpenDis.c starting line 832: 822 /* if RM database was allocated by XGetDefault() free it */ 823 if (dpy->db && (dpy->flags & XlibDisplayDfltRMDB)) 824 XrmDestroyDatabase(dpy->db); this is from the _XFreeDisplayStructure() function and the function documentation says: /* XFreeDisplayStructure frees all the storage associated with a * Display. It is used by XOpenDisplay if it runs out of memory, * and also by XCloseDisplay. .... */ So looks like there is no need to manually call XrmDestroyDatabase() anymore, attached patch removes it.
