I'm writing a simple tree checker for deep nested tables with unorthodox keys (functions, tables, userdata, threads).

I'm testing it against Lua from versions 5.1 to 5.4 but the call stack is inconsistent in newer versions while Lua 5.1 is showing the expected stack.

I wrote a simple reproducible test:

See that on Lua 5.2+ (5.4 inclusive) points to the wrong line.
A workaround is to keep the value of each call on a variable, and use it to call the next step. While I can do this, It is counterintuitive and even make debugging a hard work prone to error.
