| 10 * "The RegExp MarkupSPE in demo crashes Mozilla" | |
| 11 * | |
| 12 * See http://bugzilla.mozilla.org/show_bug.cgi?id=103087 | |
| 13 * The SpiderMonkey shell crashed on some of these regexps. | |
| 14 * | |
| 15 * The reported crash was on i=24 below ('MarkupSPE' regexp) | |
| 16 * I crashed on that, and also on i=43 ('XML_SPE' regexp) | |
