[Bug tree-optimization/19058] [4.0 Regression] setjmp: 4.0 fails to give 'clobbered' warning (regression from 3.4.1)

[rth at gcc dot gnu dot org]

The warning has *always* been specifically dependant on which registers are
assigned to which decls.  So it was never assured that you'd get the warning
when you actually needed it.

In this case you're doubly screwed because you expect gcc to magically follow
the path from "*x" through the signal handler, through to setjmp.  Well, we're
not going to do that.

INVALID or WONTFIX, your choice.
