Bug ID: 80524
Summary: Problematic behaviour with a finalization subroutine
in gfortran
Product: gcc
Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: andrew at fluidgravity dot co.uk
Target Milestone: ---

Fortran code with a finalize subroutine
When I compile and run the attached code, the subroutine 't_final' gets called
once.
> gfortran prog.f90 && ./a.out
In SUBROUTINE t_final
The PGI compiler gives the same behaviour.
However, 't_final' is called three times when the Intel (v17.0.1) compiler is
used:
> ifort prog.f90 && ./a.out
In SUBROUTINE t_final
In SUBROUTINE t_final
In SUBROUTINE t_final
I initially assumed that Intel was wrong and sent them a bug report. (It's
out-voted and the behaviour is unintuitive.) However, Intel claim that their
behaviour is correct. I shall post Intel's response in a follow-up message.
