You guys are right.. I was having memory issues...
this is somehow inconsistent...
local var_01 = ffi.new("char[5]", "default string value for var_01" );
only load the first 4 char + \0; that's logic
but
local var_01 = ffi.new("char[?]",0, "default value for var_01" );
copies the whole thing w/o allocating??
It would be good catching the 0 thing or convering it into the feature I
thought it was
Does anyone knows where in LJ source code is this implemented?
thanks

Don't do that you are corrupting memory. See that attached script.
