Pedro Alves <palves at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |palves at redhat dot com --- 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: http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00344.html
