Stackoverflow error when selector contains :Eq (ex $(":input[data="value:Equivalent"]") )

[iulian@…]

Example jsFiddle: ​http://jsfiddle.net/h9VRc/2/

Results in error: Uncaught RangeError: Maximum call stack size exceeded

Apparently the problem is in the select function:

POS handling if (matchExprPOS?.test(selector)) {

return handlePOS(match, context, results, seed);

}

where the regex is : /:(nth|eq|gt|lt|first|last|even|odd)(?:\(((?:-\d)?\d*)\)|)(?=[^-]|$)/gi

which matches selectors that contain "unintended" pseudo selectors like the one in the summary.
