[openssl-dev] Memory Leak in Crypto_Malloc

[T@Run..............! Polisetty]

Hai All,

We are running Dtls Calls and we are seeing the following Memory leaks.

 1,340 bytes in 5 blocks are still reachable in loss record 2,684 of 3,019
==22625==    at 0x4C28BED: malloc (in
/usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)

There are many leaks because of crypto_malloc, just i pasted one for sample
purpose.

My question is how to free that above allocated memory. Do SSL_free() will
clear above memory.

Could any help me in this regard.

Satya
