Reproducible Error when incidentaly leaving a stray quotation mark in a Procedure call

I was cutting a string and pasting a variable name into a procedure call (messagebox), but accidentally left the trailing quotation mark too long.

I am able to click continue and quickly delete teh offending quote mark, but if I delay too much the error recurrs.

I am running the Xcopyable version in "portable mode" but have not altered anything from "out of the box"

Details below:

This is my Exact Code:

        voidDebugStringBox(string tmpString)
        {
            if (MessageBox.Show(tmpString, tmpString, MessageBoxButtons.YesNo)==DialogResult.No)
            {
                 //some interesting behaviour here
            }
        }

If I add a quotation mark like this:

        voidDebugStringBox(string tmpString)
        {
            if (MessageBox.Show(tmpString, tmpString", MessageBoxButtons.YesNo)==DialogResult.No)
            {
                 //some interesting behaviour here
            }
        }

Then I get the following Error:
