Submodule error

[FlyingHermes]

Hi,

I think this code is correct but ifort  generate an error

Module MyModule
  implicit none
  private
  Type ,public  ::  Object
    integer     ::  NVar
  contains
    procedure   ::  DoSomething
  End Type
  Interface
    Pure Module Function DoSomething( This, Vinp ) result(Vout)
      class(Object)                   ,intent(in)   ::      This
      real(8) ,dimension( This%NVar ) ,intent(in)   ::      Vinp
      real(8) ,dimension( This%NVar )               ::      Vout
    End Function
  End Interface
End Module

Submodule(MyModule) MySubModule
  implicit none
  contains
    Pure Module Function DoSomething( This, Vinp ) result(Vout)
      class(Object)                   ,intent(in)   ::      This
      real(8) ,dimension( This%NVar ) ,intent(in)   ::      Vinp
      real(8) ,dimension( This%NVar )               ::      Vout
      Vout = Vinp / This%NVar
    End Function
End Submodule

The error is:

$ ifort -c module.f90 
module.f90: error #6121: The characteristics of the function result differ from those specified in the separate interface body.   [DOSOMETHING]
compilation aborted for module.f90 (code 1)

and I'm compiling with:

$ ifort --version
ifort (IFORT) 17.0.0 20160721

on the following system:

$ uname -a
Linux XXX 4.8.15-300.fc25.x86_64 #1 SMP Thu Dec 15 23:10:23 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

You are correct. It should compile. Steve found and reported this defect earlier (see reply #10) in this post:  https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/672035

With your test case, I confirmed the error occurs with the 17.0 initial release compiler and that with our latest 17.0 update 1 it compiles w/o the error.

Hi,

Is this one fixed in Update 4 ?

Also, is there a centralized location where to look for the submitted bugs ?

The 'Release Notes' which come with the compiler (at least, the Fortran one) are not very useful to track changes and bug fix.

Thanks.

Your issue was fixed back in PSXE 2017 Update1 as I posted in #2 earlier this year.

The fixes list for PSXE 2017 are incomplete at this time. There's a partial Update 2 list for Fortran specific issues. They are available here: https://software.intel.com/en-us/articles/intel-parallel-studio-xe-2017-composer-edition-compiler-fixes-list
