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.
