Package: dash
Version: 0.5.3-3
Severity: normal
$ [ '!' != '*' ]
[: 1: *: unexpected operator
POSIX says of the 3-argument case for test(1):
3 arguments:
* If $2 is a binary primary, perform the binary test of $1 and $3.
* If $1 is '!', negate the two-argument test of $2 and $3.
* [XSI] If $1 is '(' and $3 is ')', perform the unary test of $2.
* Otherwise, produce unspecified results.
It seems to me that dash performs the first two rules in the wrong
order. (POSIX doesn't explicitly say that these rules are ordered, I
suppose, but anything else seems to be a tortuous interpretation.)

Version: 0.5.7-4+b1
It looks like this problem has been fixed upstream and included in one
of the existing Debian packages.
Using dash 0.5.7-4+b1 I get no syntax errors and the behaviour is the
same I get using bash.
$ [ '!' != '*' ] && echo "OK" || echo "fail"
OK
