sorry for the noise: I made a mistake because the file to edit is
/usr/share/arduino/hardware/arduino/avr/platform.txt. I inserted
-fno-devirtualize as option in this line:
compiler.cpp.flags=-c -g -Os {compiler.warning_flags} -std=gnu++11
-fpermissive -fno-exceptions -ffunction-sections -fdata-sections
-fno-threadsafe-statics -MMD -flto -fno-devirtualize
and now it works as expected. Tnx for help (and patience)
