This looks like a compiler bug to me. However, GNAT 6.2.1 on Windows
reports the same access violation.

Since the access object being dereferenced is in a package level
variable, it should not be possible to get an access violation.

I don't see why interfaces should affect accessibility.
If you post a variant that works with GNAT 2009, I can try it with
6.2.1.
I suggest you report this to AdaCore.
