Preprocessed source, compiler command lines and err. output
Hello, I would like to report an repeatable internal compiler error outputs
with AVR-GCC 12.2.0 (and 12.1.0 too):
during RTL pass*: combine
Print.cpp: In function print.constprop.isra

Please submit a full bug report, with preprocessed source (by using

lto-wrapper.exe*: fatal error:
C:\Users\kovar\AppData\Local\arduino15\packages\arduino\tools\avr-gcc\avr-gcc-12.2.0-x86-windows\bin\avr-gcc
returned 1 exit status
compilation terminated
In opposite, I tested AVR-GCC 11.1 on the same source code with NO ERROR
result.
I'm attaching preprocessed source code and command line invocations with
compiler output.
