Source code

Attempting to compile the attached C++ file (BUG.cpp) produces a report of =
an
internal error:

BUG.cpp: In function 'int fetch_byte(FVM::code_P)':
BUG.cpp:16:31: internal compiler error: in type_hash_canon, at tree.c:7158
   if (ip < (FVM::code_P) FVM::CODE_P_MAX)
                               ^~~~~~~~~~
Please submit a full bug report,
with preprocessed source if appropriate.

Attachments:
BUG.cpp: source code, not a *.ii as the source is self-contained.
output: stdout/err output from compilation and "g++-avr -v"
bug: short script of commands to produce "output"

This is the compiler binary included with the Arduino IDE version 1.8.12.
I believe it is standard as the Arduino website does tell you when they have
modified source code of other components.
