Alessio Giacobbe fea85e5fcb fix(parser): propagate multi-level break/continue before trailing statements ... The flag checks that translate `break N` / `continue N` were emitted only at the end of each enclosing loop body. After the inner construct exited with the countdown flag set, every trailing statement of the enclosing body still executed before the check ran: foreach ([1] as $x) { foreach ([1] as $y) { break 2; } echo "leaked"; // ran in compiled output, not in PHP } The native (int-typed) switch path was worse: its check sat inside the do-while(0) wrapper, decrementing the flag a second time for the switch level the C++ `break` had already exited. A `break 2` from a native switch inside a loop therefore never exited the loop at all. Emit the propagation check immediately after every nested loop / switch statement instead, from the statement dispatcher, and drop the dead end-of-body emissions. The check now also distinguishes the enclosing construct: when it sits inside a switch, a continue that lands on the switch level lowers to `break`, matching PHP's continue-targets-switch semantics. parseBreak/parseContinue now reject levels exceeding the number of enclosing breakable constructs - the same compile-time validation PHP performs (`Cannot 'break' 2 levels`) - which the countdown scheme relies on to terminate at an enclosing construct. The continue-2-while scenario in break-continue-level.phpt encoded the old leaked behavior: its `$i++` after the inner loop only ran because of the misplaced check; standard PHP loops forever on it. The counter now advances before the inner loop.		2 days ago
