Error using GetOpenFileName in debug version, and not in release

Im trying this code in a dialog with only a button when you push it this code is executed:

void CBorradlgDlg::OnButton1() 
{
	// TODO: Add your control notification handler code here
	OPENFILENAME ofn;       // common dialog box structure
	char szFile[512];       // buffer for file name
	char title[]="Title openfilename";
	// Initialize OPENFILENAME

	//ZeroMemory(&ofn, sizeof(ofn));
	ofn.lStructSize = sizeof(ofn);
	ofn.hwndOwner = GetSafeHwnd();
	ofn.lpstrFile = szFile;
	ofn.nMaxFile = sizeof(szFile);
	ofn.lpstrFilter = "Object\0*.obj\0All\0*.*\0Text\0*.TXT\0";
	ofn.nFilterIndex = 1;
	ofn.lpstrFileTitle = NULL;
	ofn.nMaxFileTitle = 0;
	ofn.lpstrInitialDir = NULL;
	ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;
	ofn.hInstance=0;
	ofn.lpstrCustomFilter=NULL;
	ofn.nMaxCustFilter=0; 
	ofn.lpstrTitle=(LPSTR)title; 
	ofn.nFileOffset=0; 
	ofn.nFileExtension=0; 
	ofn.lpstrDefExt=".obj"; 
	ofn.lCustData=0L; 
	ofn.lpfnHook=NULL; 
	ofn.lpTemplateName=NULL;

// Display the Open dialog box. 

	if(GetOpenFileName( &ofn ) != TRUE)
	{
		DWORD Errval=CommDlgExtendedError();
		switch(Errval)
		{
		case CDERR_DIALOGFAILURE:	AfxMessageBox("CDERR_DIALOGFAILURE "); break;
		case CDERR_FINDRESFAILURE: AfxMessageBox("CDERR_FINDRESFAILURE "); break;
		case CDERR_NOHINSTANCE: AfxMessageBox("CDERR_NOHINSTANCE "); break;
		case CDERR_INITIALIZATION: AfxMessageBox("CDERR_INITIALIZATION "); break;
		case CDERR_NOHOOK :AfxMessageBox("CDERR_NOHOOK "); break;
		case CDERR_LOCKRESFAILURE: AfxMessageBox("CDERR_LOCKRESFAILURE "); break;
		case CDERR_NOTEMPLATE: AfxMessageBox("CDERR_NOTEMPLATE "); break;
		case CDERR_LOADRESFAILURE: AfxMessageBox("CDERR_LOADRESFAILURE "); break;
		case CDERR_STRUCTSIZE: AfxMessageBox("CDERR_STRUCTSIZE "); break;
		case CDERR_LOADSTRFAILURE: AfxMessageBox("CDERR_LOADSTRFAILURE "); break;
		case FNERR_BUFFERTOOSMALL: AfxMessageBox("FNERR_BUFFERTOOSMALL "); break;
		case CDERR_MEMALLOCFAILURE: AfxMessageBox("CDERR_MEMALLOCFAILURE "); break;
		case FNERR_INVALIDFILENAME: AfxMessageBox("FNERR_INVALIDFILENAME "); break;
		case CDERR_MEMLOCKFAILURE: AfxMessageBox("CDERR_MEMLOCKFAILURE "); break;
		case FNERR_SUBCLASSFAILURE:AfxMessageBox("FNERR_SUBCLASSFAILURE "); break;
		}
	}	
}

Debug version throws CDERR_INITIALIZATION error :confused: Release version works fine :) where is the error? Im using XP VC6 SP5 Thanks.

oh my God what a silly bug :wtf: some hours later i find the solution :-D, there was an uninitialited variable

char szFile[512]="";
