Oh, I see. That's a great idea.
I think the simplest way to do this is not to call GDB's in_prologue
directly from gdbpy_is_in_prologue, but reproduce some of its behavior
and adding a check on the return value of find_pc_partial_function
which will throw an exception if functionStart wasn't provided. This
may result in a bit of duplicated code, but in_prologue isn't that
long a function if you take the comments out so I don't think that
would be a problem. What do you think?

Indeed, will also change that.
Thanks a lot!
