--- Comment #2 from G. Steinmetz <gs...@t-online.de> ---
The following examples are presumably valid code,
don't use a function, nor alloc, but should be related :
$ cat z1.f90
program p
use iso_c_binding
integer :: a(2) = 0
print *, c_sizeof((a))
print *, c_sizeof(2*a)
end
$ cat z2.f90
program p
use iso_c_binding
character(1) :: a(2) = '0'
print *, c_sizeof((a))
print *, c_sizeof(a)
end
$ gfortran-13-20220904 -c z1.f90
