[Bug ada/37431] New: ACATS failures for alignment

[joel at gcc dot gnu dot org]

Worked on SVN trunk:
http://gcc.gnu.org/ml/gcc-testresults/2008-08/msg02355.html

c34002a and ~100 more.  Code is being generated for a byte wide access of the
stack and causing an alignment exception on an ERC32 CPU.  Compiler invocation:

According to http://gcc.gnu.org/ml/gcc-testresults/2008-09/msg01683.html this
problem is gone.  We are back down to 10 failures.  Thanks. 

Are there any remaining on that report, you want me to give you a back trace
on?

OK, that's good news.

You can open a PR for the "GNAT BUG DETECTED" and post the backtrace there.
