Thanks for Dmitry and Anthony's help, But my problem is not like Dmitry
said.
My program is a esl client. The leak is from esl client, not freeswitch.
I add the Anthony's patch code into esl.c,but it doesn't work. Each call
will cause the 20-40KB of memory growth.
I make 3 calls, the valgrind outputs like this
==14459== 90,642 (264 direct, 90,378 indirect) bytes in 3 blocks are
definitely lost in loss record 403 of 408
==14459== at 0x4A06AAA: malloc (vg_replace_malloc.c:291)
==14459== by 0x414524: esl_event_create_subclass (esl_event.c:179)
==14459== by 0x412054: esl_recv_event (esl.c:1245)

==14459== by 0x34CAA07850: start_thread (in /lib64/libpthread-2.12.so)
==14459==
==14459== LEAK SUMMARY:
==14459== definitely lost: 264 bytes in 3 blocks
==14459== indirectly lost: 90,378 bytes in 228 blocks
==14459== possibly lost: 550,082 bytes in 51 blocks
==14459== still reachable: 832,938 bytes in 840 blocks
==14459== suppressed: 0 bytes in 0 blocks
==14459== Reachable blocks (those to which a pointer was found) are not
shown.
==14459== To see them, rerun with: --leak-check=full --show-leak-kinds=all
I checked my code and no leak found. The leak may be in esl.c.
