This invokes undefined behavior in a program that includes <stdlib.h>,
which some would consider a good reason not to prefer it.

I believe the cross-jumping should definitely be done with -Os; the 
optimization
makes a useful contribution to reducing code size, which the user has 
told us
is important to him.  Other than that, I don't care much.  (I have 
debugged
problems where the debugger was showing me the wrong abort call, and
this was annoying, but not something I couldn't deal with.  Typically 
you
just have to stop on the right call to the function that's calling 
abort.)
