same problem .........

[charlesbaynham]

Hi both, sorry I missed this thread when it was opened. I'll take a look

[asjdf]

My chip is esp8266. This problem was solved after I updated my development board library.

[charlesbaynham]

Great. Do you know what version you were using when you were seeing this error? Also, @NickNifontov , what chip are you building for?

[NickNifontov]

Arduino Pro Mini Arduino 1.8.6 Arduino beta 1.9.x

[charlesbaynham]

I think this should be sorted now with 90ace2c704e015abaa0ea54fbf59611488af4ce4. Could you try compiling and running the updated examples?
