error after upgrading to version 2.1.0 of ESP8266 package

[wddean]

I'm using the "Sparkfun ESP8266 Thing Dev" board and sporadically my sketch crashes after upgrading to version 2.1.0. Downgrading to version 2.0 fixes the issue.

I face similar issues. Though I have been thinking I have issues with my program. Since simple sample program like blink LED works. I have been facing the sketch crashing since I upgraded to 2.1.0.

Please assist. Thank you.
