OK, good to know.

VMS, reproducible with a cross compiler hosted on Linux and targetted
to alpha-dec-openvms7.1.
The testcase is in Ada, with a compiler based on our internal GNAT tree
and gcc 3.2. The problem only shows up with -O2 and backend inlining.
Not an ideal combination ...
I will attempt a build with the GNAT sources from the public GNAT tree and
see if it reproduces, but this seems unlikely.
I can investigate here, so clues as to what might have gone wrong would be
appreciated. I understand this might not be easy with the only little
information available at this point.
Thanks again for your help,
Kind Regards,
Olivier
