2026-01-09Fix minilua undefined behavior in bit.tohex.Mike Pall2-4/+4
Note: this is not a vulnerability! minilua is only used during the LuaJIT build process. It only runs controlled and static Lua code (DynASM), which is entirely contained within this repo and does not trigger the undefined behavior. This change is solely for the benefit of others, who might possibly use minilua for purposes other than running DynASM. Reported by quart27219. #1424
