[sr-dev] [kamailio/kamailio] Google Sanitizers: possible memory leaks (Issue #2892)

### Description I have compiled Kamailio with `MEMPKG=sys` param and Google Sanitizers. Then started/stopped Kamailio with default config. After Kamailio stopped the produced report below. ``` ==8042==ERROR: LeakSanitizer: detected memory leaks Direct leak of 15872 byte(s) in 124 object(s) allocated from: #0 0x7f01775ed36f in __interceptor_malloc (/lib64/libasan.so.6+0xab36f) #1 0x1296835 in addstr core/cfg.lex:1605 #2 0x129660e in addchar core/cfg.lex:1589 #3 0x1287356 in yylex core/cfg.lex:1266 #4 0x12be8c2 in yyparse core/cfg.tab.c:5508 #5 0x466c2d in main /tmp/kamailio/src/main.c:2487 #6 0x7f01768a91e1 in __libc_start_main (/lib64/libc.so.6+0x281e1) Direct leak of 6784 byte(s) in 53 object(s) allocated from: #0 0x7f01775ed36f in __interceptor_malloc (/lib64/libasan.so.6+0xab36f) #1 0x1296835 in addstr core/cfg.lex:1605 #2 0x12894c7 in yylex core/cfg.lex:1395 #3 0x12be8c2 in yyparse core/cfg.tab.c:5508 #4 0x466c2d in main /tmp/kamailio/src/main.c:2487 #5 0x7f01768a91e1 in __libc_start_main (/lib64/libc.so.6+0x281e1) Direct leak of 6104 byte(s) in 9 object(s) allocated from: #0 0x7f01775ed36f in __interceptor_malloc (/lib64/libasan.so.6+0xab36f) #1 0xbf1e09 in register_module core/sr_module.c:257 #2 0xc0c31c in load_module core/sr_module.c:641 #3 0x12d3b70 in yyparse core/cfg.y:1861 #4 0x466c2d in main /tmp/kamailio/src/main.c:2487 #5 0x7f01768a91e1 in __libc_start_main (/lib64/libc.so.6+0x281e1) ``` Full report [kamailio-sanitizer.log](https://github.com/kamailio/kamailio/files/7387628/… ### Additional Information Compiled 1483ddb735c3fa3ea77b6e2d54ec67584e56e15b -- You are receiving this because you are subscribed to this thread.
