題目: Re: [pcre-dev] Max lookbehind calculation

I attempt to second try with another example:


PCRE2 version 10.33 2019-04-16
/(?<=(?<=a)b)c.*/info
Capture group count = 0
Max lookbehind = 1
First code unit = 'c'
Subject length lower bound = 1
abc\=ph
Partial match: bc
                <


Why max lookbehind=1, but not 2?
