Hi guys, I am getting an error message from Visual Studio when shutting down PJSUA, nothing serious. It may have something in common with ticket #985. The IDE does not tell any details. The situation looks as follows: Windows 7 Proffesional Visual Studio 2008 SP1 Debug build, Run (Then a call is received or not, does not matter.) (Call hangs up. Then the program starts being closed.) pjsua_destroy() called suddenly dialogue box appears: ====== Windows has triggered a breakpoint in VoiceXMLParserSIP-CAPI_dbg.exe. This may be due to a corruption of the heap, which indicates a bug in VoiceXMLParserSIP-CAPI_dbg.exe or any of the DLLs it has loaded. This may also be due to the user pressing F12 while VoiceXMLParserSIP-CAPI_dbg.exe has focus. The output window may have more diagnostic information. ====== But I have not experienced application crash outside the IDE so I do not mind it very much. Cheers - Vali
