--- Comment #15 from John Marino <gnugcc at marino dot st> ---
to all:
I built August 28 snapshot of gcc7 with Ada frontend on FreeBSD 11.0-RC2, there
was no SIGBUS and it completed the build successfully.  (Not good news for DF I
guess)

to H.J.Lu:
There's a complete log showing where in the build the SIGBUG occurs but as far
as the assembly code that causes it, I have no idea.  If you provide me some
instructions on how, maybe I can get some useful information for you.
