lua 5.2 debug.traceback & stripped chunks

["Ashwin Hirschi" <lua-l@...>]

It looks like there's a problem in the Lua 5.2 beta when debug.traceback  
encounters a chunk with its debug info stripped.

Here are the steps to reproduce it, using 2 simple scripts:


=== kick.lua ===

print "kick..."
dofile "start.lua"


=== start.lua ===

print "starting..."
print(debug.traceback())
print "done."


=== Scenario #1 : non-compiled ===

Running

	lua kick.lua --> all's well
	
produces output:

	kick...
	starting...
	stack traceback:
		start.lua:3: in main chunk
		[C]: in function 'dofile'
		kick.lua:3: in main chunk
		[C]: in ?
	done.

	
=== Scenario #2 : compiled ===

Running

	luac -o kick.lc kick.lua
	lua kick.lc --> all's well
	
produces the exact same output as scenario 1.


=== Scenario #3 : compiled & stripped  ===

Running

	luac -s -o kick.lc kick.lua
	lua kick.lc --> oops...
	
produces only:

	kick...
	starting...

and then aborts.


Can anyone confirm my findings? Thanks.

Ashwin.
