[pcre-dev] Error -26 or freezing

Hi, Philip!

Here is pcretest listing:


PCRE version 8.13 2011-08-16
/(?>(?&t)c|(?&t))(?(DEFINE)(?<t>a|b(*PRUNE)c))/s
ba
Error -26 (nested recursion at the same subject position)


if subject string is "bba" then pcretest is freezed without answer (may be
infinite loop?)

What is wrong?
Thanx.
