I just now looked at google as well, and the above error message does appear
to be part of a bug report for gcc/gnat 4.1.  So perhaps it has been fixed
in 4.3 which is why you don't see it, and there is nothing much more that
needs to be done.

N.B. I have therefore reenabled example 19 (revision 8501) to see how well
it does on systems with gnat-4.3 installed.

Andrew, I would appreciate it if you ctested the Ada examples on your Debian
unstable system.  The gnat promotion from Debian unstable to testing is in a
nasty tangle right now (the gnat package is being deliberately held back
because of a large number of package update issues) so I am not in a good
position to try 4.3 myself on my Debian testing system.

Orion, how does the Ada component of ctest work on Fedora (which presumably
also has gnat-4.3 or later)?

If all Ada examples (including example 19) run without errors for all
systems with gnat-4.3, then I think we should just note in our release notes
that gnat-4.3 provides more reliable example results than 4.1 and let it go
at that.
