Memory Leaks (HTMemory_malloc)

Greetings and Happy New Year!

We have been experiencing crashes (over time, say after 10 consecutive
requests) in our HTTP client app that uses libwww.  This application
performs POSTs of XML documents via SSL.

Here is what dbx reports on Solaris 9:

Running: Test_POST_App_sun 
(process id 5710)
Reading librtc.so
RTC: Enabling Error Checking...
signal SEGV (no mapping at the fault address) in (unknown) at 0x10

Possible leaks report  (possible leaks:       0  total size:       0 bytes)

I did not read of any outstanding memory leak bugs in libwww.  Could it be
because of the OS?

Here is how we close down a request in terminate_handler()
            ...
			    /* Delete chunk */
			    HTChunk_delete(userData->result);

			    /* We are done with this request */
			    HTRequest_delete(request);
			    request = NULL;

			    /* Close down SSL */
			    if (userData->isSecure) {
			        HTSSLhttps_terminate();
			    }

			    /* Terminate libwww */
			    HTProfile_delete();

			    /* Mailing list says this clears up all memory
problems */
			    HTAnchor_deleteAll(NULL);

			    /* Stop the event loop */
			    HTEventList_stopLoop();

			    /* Remove the handler */
			    HTNet_deleteAfter(terminateHandler);

Could it be the sequence of these close down calls?

Any help would be appreciated.
Thanks!
