No.  That this works is not an error.  Precedence rules are used
to resolve ambiguity about which of two neighboring operators
an expression belongs to.  In this case, the assignment statement
is in the middle of an operator, so to speak, so there is no
ambiguity.

Don't send a bug report about GNU grep because I won't change it just for
the benefit of some brain damaged compiler without a proper parser.
