That's a hash table no-no. More info here: http://virtualdub.org/blog/pivot/entry.php?id=259. Simplest solution is to mask the sign bit when computing a FloatHash. Another option is to treat -0 as a special case, and return the hash value for 0. 1885777 1 ahmad.saleem792 2022-07-21 13:18:34 -0700 I think it got fixed in following commit: https://github.com/WebKit/WebKit/commit/cf04259b238524f34209400f7fc0962b7473f03f I think this can be marked as RESOLVED INVALID or RESOLVED CONFIGURATION CHANGED.
