New Revision: 323687
URL: https://svnweb.freebsd.org/changeset/base/323687
Log:
Don't use a non-zero argument for __builtin_frame_address
__builtin_frame_address with a non-zero argument is unsafe and rejected by
newer gcc. Since it doesn't seem to impact the stacktrace, don't bother
with gymnastics to unwind to a different frame for starting.
