One side effect might be that the debugger is utterly confused.
Presuming one is trying to use a so-called "language-independent"
debugger.


It seems to me that a compiler for a particular language ought to be
allowed to choose its own calling conventions in at least *some*
circumstances. (Like, no debugging, the call is not inter-langage, the
call is not calling a library routine).

Have we got to the point where link-time optimizations are worthwhile?
