How so, jmp_buf is supposed to be an opaque structure.  If a program
depends on the context of an opaque structure, then it is a bug in the
program rather than the library which changes what the opaque
structure contains.  This is the whole point of using
makecontext/restorecontext instead, those structures are not designed
to be opaque.
