Internal compiler error of ifx 2023.1.0

Consider the following minimal working example:

module lib
contains
    subroutine f()
        integer::a(1)
        a=g([42])
    contains
        function g(x)
            integer::x(:),y(SIZE(x)),g(SIZE(y))  ! compiler error
            ! but replacing SIZE(y) with SIZE(x) fixes the problem
            g=x
        end
    end
end

program prog
    use lib
end

Compilation of this code with (ifx 2023.1.0) fails with `error #5623: **Internal compiler error: internal abort**`. However, replacing `SIZE(y)` with `SIZE(x)` fixes the problem. This only happens if the function is inside a procedure.

@V-T, the internal compiler error (ICE) that you reported is gone in the latest release of ifx. This release was made available earlier this week.

Check it out!

Thank you for reporting this ICE with such a small reproducer. Good to see you have a reasonable workaround.

I filed a bug report, CMPLRLLVM-48784. Will let you know when it's fixed.
