Exception.Message breaking in minidump analyses

[rupreetg]

I am debugging a minidump using CLRMD and I am getting _firstChar as null in GetStringContents method in Desktop\heap.cs file. This causes to break the if condition and we get a Object null reference exception -
if(_firstChar.Type == null)

In what scenario is _firstChar null (though I'll dig more into it as to why its null) but more important is should we be handling the scenario where we get _firstChar as null in the first place?

Because of this issue, I am not able to get Exception.Message working properly in my code. I can share the dump if required.
