getIPInfo() resets board

There have been some changes in ESP8266-port, to make it more general. This works for me:
wifi.getIP(function(data){console.log("I­PInfo",data.ip);});
wifi.getStatus(function(data){console.lo­g("ConnStatus",data);});
Actual docu is available on @tve : http://s3.voneicken.com/espruino/functio­ns.html#t_Wifi
Since Gordon takes some days off, this will make its way to actual docu next year.
There is some more info in "Espruino on ESP8266"-board in this forum, including link to actual version. Seems to me your version is an older one (?)

From my best knowledge, reset looks like a misaligned text(error message for unknown command in a class) in flash. In my actual version this does'nt come up anymore.
