Hello all,
I have application with CMFCShellTreeCtrl on one of it's dialog and it is crashing when running on some Win8 machines. It happen when tree control trying to initialize and calls SHGetFileInfo in this part of afxshelltreectrl.cpp:
int CMFCShellTreeCtrl::OnGetItemIcon(LPAFX_SHELLITEMINFO pItem, BOOL bSelected)
{
ENSURE(pItem != NULL);
SHFILEINFO sfi;
UINT uiFlags = SHGFI_PIDL | SHGFI_SYSICONINDEX | SHGFI_SMALLICON;
if (bSelected)
{
uiFlags |= SHGFI_OPENICON;
}
else
{
uiFlags |= SHGFI_LINKOVERLAY;
}
if (SHGetFileInfo((LPCTSTR)pItem->pidlFQ, 0, &sfi, sizeof(sfi), uiFlags))
{
return sfi.iIcon;
}
return -1;
}
Application was build in VS2010 on Win7 32-bit.
I could not replicate this bug on VM so I debug remotely on client PC.
I compared the values of arguments for SHGetFileInfo function, and they looked the same on my machine and the client's, except the memory addresses.

According to the call stack error occurs in some COM functions.
I am not familiar with COM so may be some one can help me to find the reason why SHGetFileInfo cause exception.
