--- Comment #15 from Natalie Perlin <natalie.perlin at noaa dot gov> ---
Quick update:=20

Software stack and model build with gnu/13.3.0 was clear from all previous
issues! So issue with the gnu/13.x.0 compiler could be considered as fixed,
thank you so much for the help here.=20


Build with gnu/14.1.0 generated more ICEs, however.=20
FYI, the compiler errors looked as following:

...register_variable_attribute.inc:56:60:
