305326 - nsXPathResult::IterateNext() does not advance to next result

Status: RESOLVED FIXED

(Core :: XSLT, defect)

Description

[:Mook]

(Will attach testcase in a moment)

Calling iterateNext() on an XPath result no longer advances to the next result;
therefore all xpath queries expecting a list become infinite loops.

Steps to reproduce:
1. Load testcase

Expected results:
Script terminates immediately; window title is "0"

Actual Results:
Script loops infinitely, until the warning comes up (at which point it can be
aborted); window title is non-zero (in my case, "8191")

Regression range: between trunk win32 nightlies of 2005-08-17-13 to
2005-08-18-07 - suspecting the checkin from 2005-08-18 02:14 as
nsXPathResult::IterateNext() appears to no longer increment mCurrentPos.
