--- 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: âlocal_indentâ 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:
