Internal compiler error of ifx 2023.1.0

[V-T]

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.

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.

@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!
