Arduino IDE 1.8.9 Compilation Error

[yaronze]

Hi,
in IDE version 1.8.8 and 1.8.9 i am getting an unpredictable compilation error while trying to upload sketch to the Arduino Uno board.
I found out that i check the last lines as remark and compile - the error is gone' than i Unchecked the lines and they are back in the code - compile successfully.
The odd error are not consistent.

any suggestions?

the Error log looks like that:

In function 'global constructors keyed to 65535_0_Pulse_Counter_MQTT_Proto_v001.ino.cpp.o':

lto1.exe: internal compiler error: Segmentation fault
