Hi Kevin,

I have already completely rewritten the code that was crashing without
saving it anywhere first. After some trials I have reproduced it in as
small example as possible. I think that the original bug was slightly
different, but since this one crashes too that should be ok for now.

To reproduce, try typing anything inside the GrandChild class. This will
trigger the completion visitor that will crash (or at least should cause
undefined behaviour). I checked this by adding an if condition that screams
if there was an attempt to read from info->templateTypes past the end of
its size.

It seems to be caused by multiple layers of templates.
