the variable's Debug Information Entry as its real type. So far, so good.
However now the debugger will expect the variable VarName to have the type
SomeType. So we need the location attribute for the variable to be an
expression that explains to the debugger how to navigate through the
expression that explains to the debugger how to navigate through the
pointers and struct to find the actual variable of type SomeType.
The following function does just that. We start by getting
