XBREAK is a mistake. It got in because the maintainers
were not paying close enough attention (it was part of a
really huge merge). It is completely non-portable, and
there is probably no good way to make it portable. Nor
does it do anything particularly useful (even if you can
stop at the return instruction of a function, your stack
frame will generally have been destroyed already).
I'm going to propose a patch that will take xbreak out.
