This has been discussed briefly in the past; for example,
http://lua-users.org/lists/lua-l/2014-03/msg00457.html, which
references another discussion on lujit maillist:
http://www.freelists.org/post/luajit/Overriding-debugtraceback. There
is also a patch to the Tilde debugger that adds the error hook to lua
5.1: https://github.com/jjensen/lua-tilde/blob/master/lib/lua/lua_5.1.3.patch.

I'd be interested in this hook as well.

> A simple tracking of call / return statements will fail if an error is thrown

Do you have a script that demonstrates when this tracking is not working?
