Hi,
I traced through the code where the leaks occur and the structures
seem to be being freed up appropriately. There could be the chance that
purify was wrongly reporting it as a memory leak but the VC6 shows the
same leaks as well. I am quite sure that the leak is in openssl code and
I am working on finding a fix. But it sure looks complicated right now.
Thanks,
Amit.
