Hello all,
I have recently installed firebug lite locally in a work project I am
working on. I get the above error on line 23329 of firebug-lite-debug.js
having run the script for the first time on chrome. This appears to be a
bug in firebug lite. Has anyone else encountered the same issue and can
anyone suggest a solution.
It would appear to have something to do with the way firebug is trying to
call the stack trace. see below
this.trace = function()
{
var getFuncName = function getFuncName (f)
{
if (f.getName instanceof Function)
{
return f.getName();
}
if (f.name) // in FireFox, Function objects have a name
property...
{
return f.name;
}
var name = f.toString().match(/function\s*([_$\w\d]*)/)[1];
return name || "anonymous";
};
var wasVisited = function(fn)
{
for (var i=0, l=frames.length; i<l; i++)
{
if (frames[i].fn == fn)
{
return true;
}
}
return false;
};
traceRecursion++;
if (traceRecursion > 1)
{
traceRecursion--;
return;
}
var frames = [];
for (var fn = arguments.callee.caller.caller; fn; fn = fn.caller)
{
if (wasVisited(fn)) break;
var args = [];
for (var i = 0, l = fn.arguments.length; i < l; ++i)
{
args.push({value: fn.arguments[i]});
}
frames.push({fn: fn, name: getFuncName(fn), args: args});
}
