XTP 13.1.
 
During startup:
XTPImageManager()->InternalAddRef();
m_pItems->SetImageManager(XTPImageManager());
 
And later:
PostQuitMessage(0);
 
Causing a crash in CCmdTarget::~CCmdTarget() for CXTPImageManager.
 
Any ideas?

Very easy to reproduce with your SDI-sample:
 
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    ...
    ...
   
    PostMessage(WM_COMMAND, ID_STYLES_CHANGE);
 
    return 0;
}
 
void CMainFrame::OnEmptyCommand()
{
    PostQuitMessage(0);
}
 
 
Probably not an issue, but still suspect that it crashes like this...

Hi,
 
I don't think PostQuitMessage is best way to terminate application - destructor of CMainFrame is not called and its reason of issue.   Just close MainWindow instead if you need quit.

I agree, but suppose some badly written code does this. Is it possible to destroy the object somehow? CWinApp::PreTranslateMessage?

Still, I don't see any reason why PostQuitMessage would need to create crash with XTP ? Isn't it a bug?
