 Hello!
 I use VC++ 2005 (sp1), boost 1_35_0
 See ** line. I have an exception at this point.

 This function (CTradeHourScheduler::IniFileName()) is used many time in my
 code. No any errors while
 programm init or while I use boost::RegEx in a programm flow.

 But, I see an exception when I create boost::RegEx while destructuor of
 some object is called.
 "Unhandled exception at 0x00470301 in TQServerII.exe: 0xC0000005: Access
 violation reading location 0x00000004."
 No memory leek.
 When I disable this function call I see no memory leek too.
 Can I use boost::RegEx in destructon? Thank you!

 Boris.



 CString CTradeHourScheduler::IniFileName(){
         TCHAR cTmpBuff[2000]={0};

         GetModuleFileName(NULL,cTmpBuff,2000);
         CString sAppPath=cTmpBuff;

         boost::RegEx Sometest;
 **      Sometest.SetExpression(CT2A(_T("^(.*)\\\\[^\\\\]+$")));          I
 have got an exception at this point while it is called from destructor
 //      std::string
         CString         strAppDir;
         Sometest.Match(CT2A(cTmpBuff));
         ....
 }
