[defns.undefined.runtime]
runtime-undefined behavior
behavior that is undefined except when it occurs during constant evaluation
[
Note
1
:
During constant evaluation,
it is
implementation-defined whether runtime-undefined behavior results in the expression being deemed non-constant (as specified in
[expr.
const]
) and
runtime-undefined behavior has no other effect
.
