If the script uses only features specified by POSIX, it's a reasonable
expectation. If it uses features that POSIX doesn't mention -- and every
shell has them -- it's not. In this case, you are using features outside
what POSIX specifies. Since GROUPS has no standard behavior, each shell is
free to make it special (bash) or not (dash).
