Fix regression in Ada aggregate assignment
A recent upstream patch of mine caused a regression in aggregate
assignment. The bug was that add_component_interval didn't properly
update the array contents in one resize case.
I found furthermore that there was no test case that would provoke
this failure. This patch fixes the bug and introduces a test.

updated size.
