It doesn't seem so. In win_dll.c it will still let the callee overwrite the item string buffer since: p == hb_itemGetCPtr( pParam )) At least where cData is initialized using SPACE(), in test_dll.prg. (maybe the rules is something else, but that was the closest I can come up with this time). Anyway, I'm trying to figure it out since 6 hours, so I give it up now and let it corrupt memory :( Brgds, Viktor _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
