2048	exception when I create boost::RegEx in destructor code flow	Boris <boris_k@…>	John Maddock	"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));
	....
}
