Issue compiling latest stable when you undefine RTC #61

Closed sorphin closed 7 years ago

sorphin commented 7 years ago

If I comment out #define RTC (Because I don't use the timer, etc).. I wind up with this in the compile output...

When I put the #define RTC back in... all is fine..

sorphin commented 7 years ago

So.. it's not specific to RTC.. I commented some other features out (commented out their defines) with RTC still enabled... still fails the same way... FYI... Arudino IDE 1.6.9 and 1.6.10 are both doing this.. (I can't go higher right now).. OS X 10.11.4

Ok.. Interesting find... After some more searching... it appears it's related to a bug with g++.... On a hunch.. I rolled back the Arduino AVR Boards package back to 1.6.11 (1.6.12 - 1.6.14 fail)... and it compiles fine..
