error loading chunk

["Victor Bombi" <sonoro@...>]

Hello,

In Lua5.1.5 I use luaL_loadstring to load a string with some code into a new
lua_State.
I thought that it would be nicer to write it as a function and then use
string.dump to provide the chunk

the result is
testgenerator.lua:42: error loading chunk: binary string: unexpected end in
precompiled chunk


in a simple test (chunk is a string with lua code, dac:setCallback is the C
function using luaL_loadstring)
dac:setCallback(chunk)
works

dac:setCallback(string.dump(loadstring(chunk)))
throws the same error as above

How this could be?

victor
