Since it's a threaded app, have you followed all the rules about
multithreaded use of libcurl? Including the rule about not calling
curl_global_init from within a thread? Have you ruled out a memory leak
happening from within an application callback?

Yes, I tried it both ways in our testing. It is not the callback -- we disabled the only one in use to eliminate the possibility.
If I can get caught up today, I will run one more set of tests.

Using /MT or /MTd, leak occurs in both debug and release versions.
