New Revision: 355374
URL: https://svnweb.freebsd.org/changeset/base/355374

Log:
  Pass 0 to __builtin_frame_address() to appease modern GCC.
  
  Modern versions of GCC warn about passing non-zero values to
  __builtin_frame_address().  Passing 1 is a cosmetic change to remove
  the db_trace_self() frame from the printed stack trace.
