One thing I am aware of is the gdb/Mac sometimes produces results
that to not fit into the MI grammar. E.g. when listing locals
it returns:   9^done,locals={{name="a"},{name="w"}}
instead of:   9^done,locals=[{name="a"},{name="w"}]

IIRC (haven't looked at it for a while) also the output for -break-insert
is different.

And (also IIRC) Mac gdb automatically creates MI variables when
running -stack-list-locals.

In case you need details (or want to be sure that I remember correctly ;-))
I can dig through my project history...
