[pcre-dev] Named subpatterns fault

Hi, Philip!

Look at this pcretest listing please:


PCRE version 8.37 2015-04-28
/(?(DEFINE)(?<a>(?:1|(?&b)(?&a))?+)(?<b>2))/ismxS+
Failed: internal error: previously-checked referenced subpattern not found
at offset 42


It seems this result is erroneous.
Thanx a lot.
