Summary: tk crashes when destroying a widget

Initial Comment:
The added script causes an coredump when startet by

	wish85.exe core.tcl

( If i start the wish and 
	source core.tcl
there is no coredump.
For me it seems that althoug there is an "tkwait variable v2" in proc dialog2 the Konsole
which ist started is still 'active'. )

I tested the script with the versions 8.4.19 and 8.5.7 on windows and linux.
The coredump only occurs on windows 8.5.7

If I add an 'update' before 
   destroy .d1
there is no core dump.

I was able to repro, but unfortunately the bug disappears when compiled
with debug symbols.

Message:
We are also hitting this bug in our Tcl/Tk 8.5.7 installation(based on the
ActiveState package).
It seems to be linked to the use of grab, which we were using quite
excessively. We have changed the code to use transient instead, which seems
to have alleviated the problem somewhat, but are still worried that it may
rear it ugly head again.
We also managed to reproduce the problem in the 8.5.6 package from
activestate(in windows xp), but not in 8.5.5.

Any chance this will be looked upon for 8.5.8 and if so, is there a
planned 8.5.8 release on the horizon?
