There's no need to "confirm" this is a bug; an internal compiler error
like this is _always_ a bug. Whether reporting it is going to result in
any action isn't clear, it may be sufficiently unusual that no one else
is likely to encounter it. Or it may be the result of a failure to
detect a user error, in which case there may be a workround.

If you can demonstrate the same error using GNAT CE 2018, it's worth
reporting to report@adacore.com (GNAT in the subject line), which may
result in a fix in due course (but probably not for a while).

If you were to upload both the sources as requested in the bug box here,
we could try to help by checking later compiler releases or looking for
a workround.
