I daily do fetch updates.

I seem to remember that some time ago, TTimer in my testing project worked.


I did some more tests:

In fact the IDE does not crash. It shows a hidden Message Window: 
"Project eventtestraises exception class 'RunRerror(201)'

The TTimer is just instantiated. I can reach a breakpoint at 
fpguiobject.inc line 151.

Stepping over same to line 153 shows a decent value for the Timer 
variable: $B761AA00.

But stepping line 153 produces the exception.Same is "Result := 
PtrInt(Timer); " This is a 32 Bit Linux aned PtrInt in fact is "LongInt".

So the Loingint will be negative and as THandle is PtrUInt which again 
is DWord, a range check exception is raised.

Changing the line to  " Result := THandle(Timer); "  makes the Timer work.

I don't know if this is appropriate for all Archs....
