--- Begin Message ---Till et al: any idea what could be causing these double-free problems? Apparently they only get triggered if both the Gutenprint and foomatic-db xml files are installed at the same time. Chris ---------- Forwarded message ---------- From: Luca Bruno <[EMAIL PROTECTED]> Date: May 29, 2006 9:21 AM Subject: Bug#362586: patch To: [EMAIL PROTECTED], [EMAIL PROTECTED] tags 362586 patch #more a workaround than a real patch ;) thanks Runnnig `foomatic-db-engine -O` in gdb says that the bug is at line 1840: 1832 if (debug) fprintf(stderr, " Printer file loaded!\n"); 1833 /* process it */ 1834 parse(&printerbuffer, NULL, NULL, printerfilename, &printerlist, 4, 1835 (const char **)defaultsettings, num_defaultsettings, &nopjl, 1836 idlist, debug2); 1837 /* put it out */ 1838 printf("%s", printerbuffer); 1839 /* Delete the printer file from memory */ 1840 free((void*)printerbuffer); 1841 printerbuffer = NULL; 1842 } Just commenting out that line fixes the glibc error. I've attached here the patch. I've tried it in printconf and it now works. Please note that this is a just a workaround, because I couldn't find a trivial double free. A better patch should be applied once identified the real issue. Theorically this could lead to memory leak (but I didn't experience in my test).
