Please include these source files with error report
Note that list may not be accurate in some cases,
so please double check that the problem can still
be reproduced with the set of files listed.
Consider also -gnatd.n switch (see debug.adb).

OK. Can you get a backtrace from gnat1 on this crash so that
we get a bit more info about where gnat1 is crashing? As I said, I
can't
reproduce it and the above info unfortunately isn't enough to
understand
what is going on.
on i686-darwin9:
