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
 
Print.cpp:112: internal compiler error  in add_clobbers, at config\avr\avr-dimode.md
   112 | }
   | ^
   libbacktrace could not find executable to open
   Please submit a full bug report, with preprocessed source (by using -freport-bug)
   gcc.gnu.org\bugs\> for instructions
 
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.
