QList<pointer>::takeFirst() and memory leak question

[AcerExtensa]

Hi All!
Can't think clearly today. So, just to be assured, has decided to ask:
I have QList created somewhere in program:

QList<ExFOLDER *> mapi_folders;
//....
ExFOLDER * folder = new ExFOLDER(CRM_ID,oid);
//...
mapi_folders.append(folder);

QList<ExFOLDER *> mapi_folders;
//....
ExFOLDER * folder = new ExFOLDER(CRM_ID,oid);
//...
mapi_folders.append(folder);

To copy to clipboard, switch view to plain text mode 

after some procedures:

while(mapi_folders.count() > 0)
{
ExFOLDER * folder = mapi_folders.takeFirst();
//...
delete folder;
}

while(mapi_folders.count() > 0)
{
ExFOLDER * folder = mapi_folders.takeFirst();
//...
delete folder;
}

To copy to clipboard, switch view to plain text mode 

Do I have memory leaks in this code sample?

yes, if an exception is thrown in line 4; no otherwise.

yes, if an exception is thrown in line 4

If you don't know exactly or if you want be absolutely sure, then use a normal iteration scope and afterward do

qDeleteAll(mapi_folders);
mapi_folders.clear();

qDeleteAll(mapi_folders);
mapi_folders.clear();

no exceptions for sure;

If you don't know exactly or if you want be absolutely sure, then use a normal iteration scope and afterward do

I have not much resources to wait for loopend... and do qDeleteAll(). WINCE Platform. Thought that Object removal when in it is no more necessity there, is good idea. The second(while(mapi_folders.count() > 0)) loop can take long time.

Thanks for yours answers!
