[Bug fortran/16674] New: Invalid code in specification expression accepted

[Mart dot Rentmeester at nn-online dot org]

In bug #15963 I reported that gfortran was inconsistent
in accepting arguments for the function 'count' when it
is used in a specification expression. This has been
fixed. That piece of code was the following:



subroutine x(a)

implicit none
character(8), intent(in)  :: a(10)
character(8)              :: b(count(a < 'D'))


write(6,*) size(b)

end subroutine x



However, I am currently testing the Absoft compiler and that
rejects the code anyway saying that 'count' is not allowed
to be used in a specification expression. After some digging
in Metcalf and Reid it appears they are right. 'count' is a
so-called 'transformational function', and those are not to
be used in specification expressions. If someone more 
knowledgable about the standard can confirm this, then this
is a bug in gfortran (and all other compilers I know because
they accept it as well).
