Welcome! Please see the About page for a little more info on how this works.
Chaining together channels apparently leaks memory in Safari.
A statement such as
(def test [input-chan] (map< identity (map< identity (map< identity input-chan))))
will leak memory when the channels are used. The longer the chain the more memory.
I have created an example repository and an example page.
The repo and the example code is here: https://github.com/bhauman/checkmemleak/blob/master/src/checking_safari_leak/core.cljs
The demonstration page is here: This link will leak http://rigsomelight.com/checkmemleak/?leak=true This link will not http://rigsomelight.com/checkmemleak
The leak is pretty darn severe.

I have just confirmed this is also a problem in Safari Version 7.0.1 (9537.73.11) on Mavericks.
I updated the example page.

This link wont leak: http://rigsomelight.com/checkmemleak/index.html#comp-partial
This link will leak: http://rigsomelight.com/checkmemleak/index.html#map<
There is navigation to try the different implementations and optimization modes.
To be clear map<-chain, custom-map, map<, and map> all exhibit the leak in :none and simple optimization modes.

To make sure this ticket has all the necessary information - if I remember correctly even advanced optimization is affected? Am I correct Bruce?
Yes, it affected advanced optimization. I haven't checked if this is still an issue.
