- Subject: warning using luaL_newlib

I have a line of code in my Lua module source which looks like this:
luaL_newlib(L, functions);
'functions' is of type 'const luaL_Reg *'
The module compiles fine, but issues a warning:
‘implicit conversion from 'unsigned long' to 'int' changes value from
18446744073709551615 to -1’.
It doesnt appear to be happening anywhere in my code. How do I make
this go away?
Full output is below:
src/luaharfbuzz/class_utils.c:12:3: warning: implicit conversion from
'unsigned long' to
'int' changes value from 18446744073709551615 to -1
