CFSocket & SSLHandshake

Greetings...

I've been working on a Cocoa wrapper for CFSocket that also takes advantage of the SSL functionality in the Security framework. My socket wrapper works just dandy for non-SSL connections -- CFSocket makes life easy. However, I'm seeing some very strange issues when I create and destroy several SSL connections in sequence. I'm working on creating a simple, sample test program that can demonstrate. For the moment, though, I do have a symptom to report.

I'm using a BSD socket in non-blocking mode. The first time I call SSLHandshake, everything is fine -- I may have to call it twice, depending on network conditions -- but I get a normal (read: 0) result code. Second time through, I've constructed a new CFSocket, new wrapper, etc. On this pass, my first call to SSLHandshake returns errSSLWouldblock. I call SSLHandshake again and I get a warning on the console:

*** malloc_zone_malloc[803]: argument too large: -69

SSLHandshake then returns an error code of -50. Obviously this is...sub-optimal. :)

Has anyone seen anything like this before?

Thanks. :)
