-Subject: [PATCH] json_escape_str(): avoid harmless unsigned integer overflow
-
-Current behaviour is perfectly valid, since wrap-over upon overflow is
-well defined behaviour for unsigned types, but it is nevertheless nice to be
-able to build with -fsanitize=undefined,unsigned-integer-overflow
-
-There is no significant effect on the generated assembly as can be seen
-on the diff of objdump -d output on a optimized build (the compiler
-just decided to switch the order of a comparison):
