Empty "while" statement causes crash

[Willard21]

An empty while statement crashes with the completely useless "Something's wrong with the HTML but we're not sure what" message in the webpage environment. The PJS environment crashes too, but it at least gives a line number and an explanation.

To Reproduce:

var i = 10;
while(--i);

Expected Behavior:
It should just work. This is valid Javascript. Or if the more "standard" syntax is desired, it should give a line number pointing to the problem.

Thanks for the report, Willard! I reproduced as well.
