I have experienced a strange bug where a program is not executed when there is
an additional while loop in a function that is not even used. Here's my code.
This is the code that let's the program start. The bad thing is commented out.
Tested with 0.2.8 Livecd.

[code]
// This function is not called!!!
BOOL FolderCB_Init(HWND hwndCB)
{
	IShellFolder *psfRoot, *psfDrives;
	IEnumIDList	*lpeRoot, *lpeDrives;
	LPITEMIDLIST pidlDrives, pidlTmp, pidlTmp1, pidlAbsTmp;
	ITEMIDLIST idlAbsTmp[2];
	LPMALLOC pMalloc;

	SendMessageA(hwndCB,CB_SETITEMHEIGHT,-1,(LPARAM)GetSystemMetrics(SM_CYSMICON));
	SendMessage(hwndCB,CB_SETITEMHEIGHT,0,(LPARAM)GetSystemMetrics(SM_CYSMICON));

	SendMessageA(hwndCB,CB_SETEXTENDEDUI,(WPARAM)(TRUE),0);
	SHGetSpecialFolderLocation(0,CSIDL_DESKTOP,&pidlTmp);
	FolderCB_AddItem(hwndCB, pidlTmp,-1,0);
	SHGetSpecialFolderLocation(0,CSIDL_DRIVES,&pidlDrives);
	SHGetDesktopFolder(&psfRoot);

	if (SUCCEEDED(SHGetMalloc(&pMalloc)))
	{
		if (psfRoot)
		{
			if(SUCCEEDED(IShellFolder_EnumObjects(psfRoot, hwndCB, SHCONTF_FOLDERS,
&lpeRoot)))
			{
				while (S_OK == IEnumIDList_Next(lpeRoot, 1, &pidlTmp, NULL))
				{
					FolderCB_AddItem(hwndCB, pidlTmp,-1,1);

					if (memcmp(pidlTmp, pidlDrives, sizeof(ITEMIDLIST)) == 0)
					{
						if(SUCCEEDED(IShellFolder_BindToObject(psfRoot, pidlTmp, NULL,
&IID_IShellFolder, (LPVOID*)&psfDrives)))
						{

							if(SUCCEEDED(IShellFolder_EnumObjects(psfDrives, hwndCB,SHCONTF_FOLDERS,
&lpeDrives)))
							{
//this doesnt work in ROS:						while (S_OK == IEnumIDList_Next(lpeDrives, 1,
&pidlTmp1, NULL))
IEnumIDList_Next(lpeDrives, 1, &pidlTmp1, NULL); // this fnction is not the problem
while (FALSE) // the while is the problem, but not "while(FALSE)".
								{
									pidlAbsTmp = ILCombine(pidlTmp, pidlTmp1);
									FolderCB_AddItem(hwndCB, pidlAbsTmp,-1,2);
									pMalloc->lpVtbl->Free(pMalloc, (void*)pidlAbsTmp);
									pMalloc->lpVtbl->Free(pMalloc, (void*)pidlTmp1);
								}
								IEnumIDList_Release(lpeDrives);
							}
							IShellFolder_Release(psfDrives);
						}
					}
					pMalloc->lpVtbl->Free(pMalloc, (void*)pidlTmp);
				}
				IEnumIDList_Release(lpeRoot);
			}
			IShellFolder_Release(psfRoot);
		}
		pMalloc->lpVtbl->Free(pMalloc, (void*)pidlDrives);

		SendMessage(hwndCB, CBEM_SETIMAGELIST, 0, (LPARAM)himlSystem);
	}
}
