* SUMMARY: Arose from Bugzilla bug 103087:
* "The RegExp MarkupSPE in demo crashes Mozilla"
*
* See http://bugzilla.mozilla.org/show_bug.cgi?id=103087
* The SpiderMonkey shell crashed on some of these regexps.
*
* The reported crash was on i=24 below ('MarkupSPE' regexp)
* I crashed on that, and also on i=43 ('XML_SPE' regexp)
