It's not a bug.

Historical versions of `test', including the version built into earlier
versions of the System V sh, used that `operator' to calculate string
length.  It's no longer needed now that we have the ${#paramter} expansion,
and it screws up the grammar.

It's not in the POSIX.2 spec for `test', and bash no longer supports it
(and has not for quite a while).
