It works as expected. Apparently any number (withing the bounds of a byte) works except for 128.

Without the while loop it is ok. So this works... ``` void setup() { Serial.begin(115200); } void loop() { for (byte i = 0 ; i < 128 ; i++)...

This works... ``` void setup() { Serial.begin(115200); } byte i; void loop() { while (1) { for (i = 0 ; i < 128 ; i++) { Serial.println(i); } }...

Can you point me to the gcc bug tracker that I should report this to?

Really didn't feel qualified to report the gcc bug but I did and provided a link back to here. Thanks for everyone's work on this! https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90886

Looks like gcc.gnu.org isn't supporting 5.4.0 or 7.3.0.

That is correct.
