The return value of argv_assemble is owned by the caller and should be free'd. When processing the sSubsystem case there are two calls to argv_assemble but only one of them is freed. This patch fixes the small (29 bytes according to valgrind) memory leak. The output from valgrind: ==115369== 29 bytes in 1 blocks are definitely lost in loss record 573 of 913 ==115369== at 0x4845794: malloc (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so) ==115369== by 0x124A22: argv_assemble (misc.c:2165) ==115369== by 0x1385E5: process_server_config_line_depth.constprop.0 (servconf.c:2004) ==115369== by 0x13984D: parse_server_config_depth.constprop.0 (servconf.c:3032) ==115369== by 0x139986: parse_server_config.constprop.0 (servconf.c:3049) ==115369== by 0x111C6E: main (sshd.c:1445)
