(This bug description assumes that the patch to PR30520 is already applied.)
gfortran currently permits the following redundant VOLATILE attributes:
module A
real :: vol
end module A
module B
use A
volatile :: vol
volatile :: vol ! WRONG, but accepted
end module B
gfortran wrongly rejects the following VOLATILE:
module test
real, volatile :: A
contains
subroutine sub
volatile :: A ! VALID, but rejected
end subroutine sub
end module test
Check: In the following example, the variable "global" should only be volatile
in subroutine A. Does this really happen?
program test
real :: global
! global should not be volatile here
contains
subroutine A
volatile :: global
end subroutine A
subroutine B
! global should not be volatile here
end subroutine B
end program test
