--- Comment #1 from Pedro Alves <palves at redhat dot com> ---
(Repeating my comment on the GDB bugzilla here)

All these warnings are around setjmp/longjmp.

E.g, with:

.././../src/gdb/python/py-framefilter.c:731:11: error: ‘local_indent’ may be
used uninitialized in this function [-Werror=maybe-uninitialized]
       int local_indent = 8 + (8 * indent);

local_indent is only used in a TRY_CATCH block, meaning, after a setjmp.

I suspect this to be related to this recent setjmp gcc change:
