[lazarus] Hints and Lazarus hang on startup - compiler problem?

[Jarto Tarpio]

I've been able to reproduce systematically a problem that's related 
to the HintTimer in uniteditor.pp. Apparently Shane has also tried 
to hunt this down?

The problem appears when I move the mouse over the 
sourcenotebook while Lazarus starts. The mousemoves fire events 
at TSourceNotebook.EditorMouseMove where FHintTimer is 
disabled and enabled again to reset the delay before showing a hint.

Here's where it gets interesting. Just add a "var a: Integer;" and 
nothing else to TSourceNotebook.EditorMouseMove and it doesn't 
crash any more. This is with fpc-1.0.5-laz.20010815

I then added a global integer and increased it after every 
FHintTimer:=false in EditorMouseMove. It runs 3-7 times before it 
hanging. The timer itself doesn't hang though. Just the notebook 
form.
