The string API is a default Lua 5.1 API as defined here. Please list any non-working functions below.
Non-Working Functions
string.gmatch(string, pattern)
Using any quantifier other than + will cause it to hang if that quantifier applies to the whole pattern and that pattern does not match the whole string.
Examples:
"abcdef":gmatch("%a*") -- Works
"abc=def":gmatch("%a*") -- Hang
"abc=def":gmatch("%a.*") -- Works
"abc=def":gmatch("[%a.]*") -- Hang
"abc=def":gmatch("[^=]*") -- Hang
"abcdef":gmatch("[^=]*") -- Works
"abc=def":gmatch("[^=]*=") -- Works
