No, just that by default, when you build GDB from source (or pretty much any
other package using autotools), it defaults to using the /usr/local prefix.=
  So
my local build was looking for separate debug info in /usr/local/lib/debug,
didn't find the required debug info, and therefore didn't crash.  By tellin=
g it
to search in /usr/lib/debug, it finds the debug info and hits the bug.

You can disable the frame-filter by with the "disable frame-filter" command.
Then confirm it is disabled with "info frame-filter".
