I created a veryu complex javascript onto jquery 1.4 and it was (nearly) perfectly working with 1.4.2 (I mean : it consumes a lot of RAM to make browser crashes very frequently).

Since 1.4.3 and 1.4.4 , $.post() command goes to javascript halts :

**** Firefox 3.6.12:

uncaught exception: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: https://myservice/interface/stage1.js :: anonymous :: line 5767" data: no]

the calling offender :

$.post(document.location,{action:'fresh' , ordre:"{\\"0\\":[\\"fonctions\\",\\"perso_message\\",\\"commandes\\"],\\"1\\":[\\"raccourcis\\",\\"suggestions\\"]}"},function(datas){ return something; },'json');

the lines 5762→ 5767 are :

ajax: function( origSettings ) {

var s = jQuery.extend(true, {}, jQuery.ajaxSettings, origSettings),

jsonp, status, data, type = s.type.toUpperCase(), noContent = rnoContent.test(type);

console.log(s.url);

console.log(rhash);

s.url = s.url.replace( rhash, "" );

s.url : Object { constructor={...}, href="https://myservice.../", more...}

rhash : /#.*$/

**** Chrome 6:

s.url : Object Location {

assign: function () { [native code] }

hash: "#.*$/"

host: "myservice..."

hostname: "myservice..."

href: "https://myservice.../#.*$/"

pathname: "/"

port: ""

protocol: "https:"

reload: function () { [native code] }

replace: function () { [native code] }

search: ""

toString: function toString() { [native code] }

valueOf: function valueOf() { [native code] }

__proto__: Location

}

rhash : /#.*$/

Failed to load resource: the server responded with a status of 404 (Not Found)

/undefined

**** Personnal note :

I believe the problem came from document.location which was not seen as an string anymore

Firefox doesn't like regex on objects, Chrome respond to the .replace by "undefined"
