VS IDE just disappears when changing signature of VB method

[DzonnyDZ]

Version Used: VS 2015 U1 14.0.24720.00

Steps to Reproduce:

1. I have following header of VB function Public Function CreateConversionDelegate(Of TFrom, TTo)(conversion As Func(Of TFrom, TTo)) As Func(Of TFrom, TTo)
2. I'm trying to add one more parameter in front of the conversion parameter
3. So I start typing new parameter name just between ( and conversion
4. No later than I type space after the parameter name Visual Studio crashes in a weird way

Expected Behavior:
No crash

Actual Behavior:
VS just turns off. No "Visual Studio stopped working" dialog as usual. It just disappears. See attachment, what I found in event log. (Unfortunately, Git Hub seems not to support EVTX files, so I'm attaching it ZIPped)

Unfortunately Git HUB does not allow me to attach the event log even when zipped.

I was able to repro this by typing something As before the conversion parameter below:

<Assembly: CLSCompliant(True)>

Public Class C
    Public Function CreateConversionDelegate(Of TFrom, TTo)(conversion As Func(Of TFrom, TTo)) As Func(Of TFrom, TTo)
        Return Nothing
    End Function
End Class

Module Conversion

End Module

From @DzonnyDZ's event log which I got by email, the stack was:
