Re: bug in sh, probably, with test case

What are your thoughts about adopting DASH (the Debian Almquist Shell)? It is a direct descendant of NetBSD's shell from back in 1997. It is (mostly?) BSD licensed.

DASH is the most conformant shell I've seen. I have yet to find a conformance bug in DASH, and I really push shells to their limits.

Who knows if the code meets NetBSD's standards, but it does compile without warnings on amd64 and seems to run OK. I don't know how it differs in implementation-defined behavior, so it's possible all sorts of non-portable scripts will break.

DASH is the default /bin/sh for Debian and its derivatives (Ubuntu, Mint, etc.) so it is well exercised.
