<<
Note that C380004 "doesn't count" and should be made a XFAIL because it
raises a complex implementation issue with arrays of protected types that's
extremely unlikely to affect any real program and thus won't be fixed soon.
It'll fail with every GCC version: which targets it fails on depends on
word-size and overflow-handling issues.

<<
we should probably just reject such a large array of entries as being
a capacity limitation. It's plain silly to spend time on this :-)

Confirmed, via the testsuite run and moving to minor as this is a off in left field case.

Note that this test has been deactivated vi testsuite/ada/acats/norun.lst
so it doesn't show up in testresults anymore.
