--- Comment #1 from Ali Cehreli <acehreli@yahoo.com> ---
For completeness, here is the error message:

src/rt/dwarfeh.d:330: uncaught exception reached top of stack
This might happen if you're missing a top level catch in your fiber or signal
handler

However, only the first of the three workarounds makes the bug disappear for me. Modifying or removing Result.a or removing 'dummy' did not remove the bug.

Only removing align(16) removed the bug.

There is no issue with -m32.

Yeah, sorry about that. I guess I should've stated more clearly that the actual manifestation of the issue is that wrong argument is being passed.

I have no doubt that concrete behavior could vary. In my own codebase making
the function extern(C) also works around the bug (can't test it trivially in
this reduced case).

run.dlang.io shows the asserts fail on "all compilers" (which it starts from
2.060), though one would need to change main to this (otherwise it just shows
empty 'Server error:'):

void main(string[] args)
{
    actual = &args[0];
    actual.bug(Param.init, 0, {}, {});
}
