2192. Constant expressions and order-of-eval undefined behavior

Section: 7.7  [expr.const]     Status: open     Submitter: Peter Sommerlad     Date: 2015-10-27

Notes from the November, 2016 meeting:

CWG did not wish to require implementations to detect this kind of undefined behavior in determining whether an expression is constant or not, but an implementation should be permitted to reject such expressions. These should be indeterminately sequenced, not unsequenced.
