VisualD: VisualDComServer.exe crashes frequently inside D_Parser.dll to stackoverflow.

[Random D-user via Digitalmars-d-ide]

I've been playing more with this and it seems that now my 
msvc2013 shell also crashes from time to time. But I think it 
only crashes after VisualDComServer.exe has crashed first.

So, it looks like the issue might be editor/visuald trying to 
build a "data tip" on mouse hover.
That would match your tool tip guess. And I guess this could also 
explain why it's so random, since the mouse cursor probably just 
randomly hovers on top of some code while I type.

Perhaps I just need to bite the bullet and try to build 
visualDComParser myself so that I can debug what's wrong with it. 
(no promises though :))

Anyway, the msvc2013 crash exception is:

-$exception	{System.AccessViolationException: Attempted to read 
or write protected memory. This is often an indication that other 
memory is corrupt.
