BTW, after too many years learning to only use C functions and variables
in GDB (and not macros, CPP constants, or other compile-time-only
thingies), I only recently started to extend my GDB world.
Along the way I discovered that while `sizeof` works great, `offsetof`
gives me an error:
No symbol "offsetof" in current context.
any idea why this is (and how to fix it)?
