SpiderMonkey was updated to mozjs24. If you want to build elinks with ecmascript support, you must compile using g++ with -fpermissive . There is a lot of warnings. There are some memleaks in ecmascript code, especially related to JSAutoCompartment. I don't know yet, where and how to free it. Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
