I don't know what NPE is, but if you program with DbC your nulls are very often found out by asserts, so you have assert errors (that show line number & file name) instead of segfaults. > Sorry, didn't mean to reopen a can of worms, just wanted to be clear. When people that discuss are polite there is no problem in reopening the can now and then :-) Bye, bearophile
