Regression: crash compiling do{} while() loop

      Use of a do() while loop crashes 

      function crash()
{
    var x = -1;
    do {
        if (x >= 1) {
            x = 0;
        }
    } while (x != 0);
}

      5.3 works fine. 5.4 crashes on load.

      Naturally the example above would infinite loop and be rubbish, but it's a simplified version of more legitimate code.
