--- Comment #9 from anlauf at gcc dot gnu.org ---
Changing component from fortran to driver after brief discussion:
https://gcc.gnu.org/pipermail/fortran/2026-May/063915.html
The expected behavior (see below) existed in 8.5.0 and likely until r9-3689,
when gcc/d/lang.opt was added defining an Alias
fcheck=bounds
D Alias(fbounds-check)
However, the language seems not to be taken into account when applying
the alias.
So in some (technical) sense this is a regression which likely started
after version 8.5.0.
Note: in 8.5.0
gfortran -fcheck=bounds -fcheck=no-bounds
works as expected, while
gfortran -fbounds-check -fcheck=no-bounds
does not. In gfortran -fbounds-check is treated differently from the
generic form -fcheck=, which is why the Alias poses a problem for languages
other than D.
