GCC Configuration, Output error and sensor.i file



internal compiler error: Segmentation fault building sensor.c



I have attached a zip file thta includes the GCC configuration, compiler output

log and the sensor.i file.



I am using CooCox CoIDE 1.7.1 to edit, build and debug.



This error only happens with -O3, all other levels of optimization work fine. 

I plan to use -Os, I was just trying to compare final build sizes.



If additional information is need, please advise.
