--- Comment #3 from David Carne <davidcarne@xxxxxxxxx> 2011-02-02 14:16:48 PST ---
I ran into this issue today as well - I suspect that this is due to the use of
col_set_str in wslua_pinfo.c:Columns__newindex

col_set_str simply stores the pointer passed to it, and luaL_checkstring
returns a temporary pointer. Changing col_set_str to col_add_str in
Columns_newindex seems to fix the issue, but I haven't tested it fully.

As a workaround - use pinfo.cols.src:set("THE STRING") rather than
pinfo.cols.src="THE STRING". This method of assignment uses col_add_str which
stores the string internally rather than by storing the pointer.
