switch statement and multiple default cases

Heya, The spec states "There must be at most one default label." [1] which is surely the right way to go IMO but not even the PHP implementation (5.5.9) behaves like this and the following is perfectly valid: $a=1; $b=0; switch($a) { default: $b += 1; break; default: $b += 2; } echo $b; //output would be 2 Should I report a bug?
