Sorry for my old school gcc'ish args sir. I reached for what I knew, the Arduino IDE is a proprietary (tho free) JAVA blob to me.
The IDE or its underlings get into a forkfest. I'm on a standard pi3. 4 rocking ARM cores, 1G RAM.
How do I prove from the CLI the IDE goes nuts? let me try...
leem@testpi:~ $ grep -c processor /proc/cpuinfo
4
leem@testpi:~ $ head -1 /proc/meminfo
MemTotal: 948308 kB
leem@testpi:~ $ uname -a
Linux testpi 4.19.50-v7+ #896 SMP Thu Jun 20 16:11:44 BST 2019 armv7l GNU/Linux
leem@testpi:~ $
So a typical pi3b running debian buster.
Load Blink.ino posted earlier into IDE. Press complile...

HANG FOREVER, Find the power cord.... Last I checked i had 4 cores,not ~40.
It's repeatable, but 1.8.5 is rocking hard for me on same OS, sketch, etc.
