42 * SUMMARY: Parser recursion should check stack overflow
44 * See http://bugzilla.mozilla.org/show_bug.cgi?id=192414

49 var BUGNUMBER = 192414;
50 var summary = 'Parser recursion should check stack overflow';
54 var actualvalues = [];
56 var expectedvalues = [];
59 * We will form an eval string to set the result-variable |actual|.
60 * To get a feel for this, suppose N were 3. Then the eval string is
61 * 'actual = (1&(1&(1&1)));' The expected value after eval() is 1.
63 status = inSection(1);
65 var left = repeat_str('(1&', N);
66 var right = repeat_str(')', N);
67 var str = 'actual = '.concat(left, '1', right, ';');
75 * An exception during this eval is OK, as the runtime can throw one
76 * in response to too deep recursion. We haven't crashed; good!
