--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
build_translation_unit_decl is called exactly _once_ ... but it looks like the
linemap operation screws up sth.

Compiler command I used for reproducing:

> ./f951 -quiet aermod.f90 -fno-checking -Ofast -march=core-avx2 -funroll-loops
