To reproduce the bug, I changed the name server address in /etc/resolv.conf to 192.168.101.1 which ignores DNS packets, started "env -u http_proxy LANG=C .../elinks -no-home -no-connect http://www.debian.org/"; (without -no-home for those versions that don't support it), and pressed Q when "Looking up host" or the corresponding Finnish words appeared in the status line. Test results with various versions: ELinks 0.3.2 (links rather than src/elinks) does not crash. ELinks 0.4pre5 and 0.4pre6 (src/links rather than src/elinks) do not report a memory leak but rather crash like this: (gdb) bt #0 0x08094e02 in debug_mem_free ( file=0x80d35c0
