Well, it certainly looks like it. But I've made every possible check
to make sure all the settings are the same both building libcurl and
the app. More over, no problems occur if libcurl.dll is used instead
of static library. The only thing that comes to my mind is that
CWinThread and AfxBeginThread draw some other hidden MFC memory
allocation stuff in. May this be the problem?

TIA
