Fix a one-byte buffer underflow (read access only).
This change touches code that only runs when REG_BASIC is given and
the regular expression is anchored with ^ _and_ uses backreferences.
The segfault could only be triggered when the ^ anchor was inside
a leading () subexpression quantified with *.
