I build jsc for armv7 use softfp, when i run the following code, i get segmentfault

  var start = 1;
  function cb() {
	  var arr = [];

	  seg( function(n) {
	  	console.log(n);
	  	arr.push(n);
	  }, start);
  }

  function seg(f, n)
  {
  	f(n);
	if(n > 1000)
	  return;
  	seg(f, n+1);	
  }

  cb();

I guess stack overflow so i increase stack size, but i still get segmentfault. Each death functions are executed 66 times. stack in  SpeculativeJIT::runSlowPathGenerators

When I close JIT,use LLINT ,I success. So I guess this is Bug for JIT
