Bug ID: 65079
Summary: -Werror= does not work on implicit-procedure warning
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: nathanael.huebbe at informatik dot uni-hamburg.de
System: Ubuntu
Affected gfortran versions: at least 4.7.2 and 4.8.2
Description:
Compiling this fortran code
module bar
implicit none
contains
subroutine baz()
call bim()
end subroutine
end module
program foo
use bar
call baz()
end program
with the call
$ gfortran -c -Wimplicit-procedure -Werror=implicit-procedure foo.f90
correctly produces the warning, but fails to turn it into an error.
The behavior is the same if `-Wimplicit-procedure` is absent, and if
`implicit-procedure` is replaced by `-Wimplicit-interface`.
