In Kvrocks we faced an integer overflow detected by UBSAN in basic_json_parser.
/home/runner/work/kvrocks/kvrocks/build/_deps/jsoncons-src/include/jsoncons/json_parser.hpp:180:74: runtime error: signed integer overflow: 2147483647 + 2 cannot be represented in type 'int'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior /home/runner/work/kvrocks/kvrocks/build/_deps/jsoncons-src/include/jsoncons/json_parser.hpp:180:74 in
The reason is that we set max_nesting_depth to numeric_limits::max(), so that max_nesting_depth + 2 leads to overflow.
Here I use an equivalent form to eliminate the problem.
