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

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

I went through hovering all the symbols and it turns out that the 
bindings in Derelict lib actually trigger the crash.
 From there I managed to quickly do a small repro case that 
crashes for me in completely new empty visuald project:

module mytest;

int function(uint) TestCase;
TestCase test;

class TestClass
{
     this()
     {
         test(); // <--- hover on this
     }
}
