IFC ICE on spurious USE in submodule

[andrew_4619]

I installed the latest OpeAPI today , I was a version behind latest. I decided out of interest to try IFX in a 'large' project something I have deliberately  avoided. Anyway it successfully compiled bunch of files with several hundred thousand lines of code except for a couple of ICEs which were both the same root cause , an invalid 'self USE' within a submodule. A short reproducer is shown below.

module duff_use
    implicit none(type, external)
    interface
       module subroutine hw1_user()
       end subroutine hw1_user
    end interface
    interface
       module subroutine hw1()
       end subroutine hw1
    end interface
end module duff_use
submodule (duff_use) du1
    implicit none(type, external)
    contains
    module subroutine hw1()
        write(*,*) 'hello world'
    end subroutine hw1
    module subroutine hw1_user()
        !use duff_use !<<<<<<<this line give error #6406: Conflicting attributes or multiple declaration of name
        use duff_use, only: hw1  !<<<<<<<this line gives ice in IFX
        call hw1()
    end subroutine hw1_user
end submodule du1

The reproducer, note lines 19 and 20. I think "Module subroutine" and "use only" are essential for the ICE.

Unrelated but when I download OneAPI I got a email from the registration centre with a product key and the note "You will be prompted to enter your product key during installation" I don't get why and didn't need it. A bug in the system because I happen to be logged in maybe?

Thank you for the reproducer! Short and sweet!

I filed a bug report, CMPLRLLVM-44484.

As for the license key, there is no need for a license key with oneAPI as you know. What package did you download?

[andrew_4619]

I downloaded w_HPCKit_p_2023.0.0.25931_offline.exe and w_BaseKit_p_2023.0.0.25940_offline.exe for ****WINDOWS****!!!

The weird email that arrived a few moment later was (redacted):

Thank you for registering the Intel® oneAPI HPC Toolkit for Linux* (all tools)

Windows? Linux? WOW!

I asked the team that delivers the packages to you about this.  They ask, "How did you register for the product?"

[andrew_4619]

 "How did you register for the product?" I didn't!   I just went to the OneAPI page and downloaded, I had just been on the forum so would have been logged in but I had not been to the registration centre.  It isn't a problem (for me) but I mentioned this as I suspect something on your side is probably foobahed.

The Lord moves in mysterious ways, she has a sense of humour. 

I find this often helps to pass by the unexplainable.  

That or when someone shows you an unsolvable problem on a computer say with a Fortran program dxf file not loading on Autocad and the system is hung, pull the plug and tell them life is to short for this ______________

On the Lakeland CAM website last night in the old weekly pictures they had Wild Boar sausage rolls in the lake district, worth a flight from Houston by the looks.

Thank you! I passed the info along.

The team that manages the package distribution found the problem with that email message and fixed it!  They send along their THANK YOU!

The ICE is melted for this issue with ifx 2024.0.0 that was released this week. Please try this latest version.
