About VS2013 after the optimization of the MFC file read failure parsing (debug can, release under the failure)

Tested By:

Error from: The following program, under the VS2010 use getfilename (), the file can be read successfully, but under VS2013, use getfilename () read the file under Debug can, However, after the release fails, instead of getpathname (), it can be compiled successfully.

CFileDialog Filepclouddlg (TRUE);

if (Idok==filepclouddlg.domodal ())
{
