[openssl-users] Potential memory leak in RSA_private_decrypt

[Wang]

Hello Rich,

Thank you for trying to help. 

My product is running on Linux. The following leak was detected by Valgrind.
Valgrind only reportes
the leak in threaded mode. I run 'top' on linux to monitor the memory usage
of my product. I can see the memory usage increases quickly.

==9721== 520 bytes in 1 blocks are indirectly lost in loss record 1,178 of 
1,294 
==9721==    at 0x4A0817C: malloc (vg_replace_malloc.c:298)
