Same issue with variants ...

$ cat z2.f90
program p
   integer, parameter :: n = 2
   integer, parameter :: a(2.) = 1
   integer, parameter :: b(n, n) = reshape([a, -a], [n, n])
end

$ cat z3.f90
program p
   integer, parameter :: n = 2
   integer, parameter :: a('2') = 1
   integer, parameter :: b(n, n) = reshape([a, -a], [n, n])
end

$ cat z4.f90
program p
   integer, parameter :: n = 2
   integer, parameter :: a(.true.) = 1
   integer, parameter :: b(n, n) = reshape([a, -a], [n, n])
end

$ cat z5.f90
program p
   integer, parameter :: n = 2
   integer, parameter :: a((0.,1.)) = 1
   integer, parameter :: b(n, n) = reshape([a, -a], [n, n])
end


Same issue with other intrinsic types, and without parameter attribute for b.
