Summary: Warning format regression
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: physiker at toast2 dot net
Target Milestone: ---
When compiling the file t.f90 gfortran-7 prints the marker 1 under the second
argument. When the file is compiled by gfortran version 6 or earlier, the
marker is printed under the first argument, a, in the call to the subroutine s.
t.f90
program p
real(4) a, b
call s(a, b)
print *, a, b
end program p
subroutine s(a, b)
real(8) a, b
a = 10.0
b = 2*a
end subroutine s
gfortran-7 -W -Wall t.f90
t.f90:3:14:
call s(a, b)
1
Warning: Type mismatch in argument »a« at (1); passed REAL(4) to REAL(8)
