A particular debugger is crashing when it's trying to display the contents of a particular string in a tooltip.
I am using that particular debugger to debug the crash. In that debugger, I have a callstack in the tooltips code, and if I hover over variable containing the text that it's trying to display, I get the crash!
If I were to debug that crash, I would get a callstack in the tooltips code, which if I hovered over the variable containing the text...
You get the idea: a recursive repro case!
