The following code causes current mainline gfortran to produce warnings
about unused variables that are somewhat confused.
module test
contains
subroutine sub1 (arg1)
integer arg1
integer var1
end subroutine
subroutine sub2 (arg2)
integer arg2
integer var2
call something(arg2)
end subroutine
end module test
[EMAIL PROTECTED]:~/tmp> gfortran -c -Wunused test.f90
test.f90: In function sub2:
test.f90:4: warning: unused variable var2
test.f90: In function sub1:
test.f90:12: warning: unused variable arg1
test.f90:12: warning: unused variable var1
The diagnostics appear in the wrong order, and the line numbers are confused.
This is most likely related to (or identical with) PR21918.
