Title:
libPCRE3 8.31 regex matching is not working
Status in pcre3 package in Ubuntu:
Invalid
Status in poco package in Ubuntu:
Confirmed
Bug description:
It looks like that libPCRE3 8.31 included in Ubuntu 13.10 does not
handle regex matching alright. This also affects the libPocoFoundation
RegularExpression classes.
I attached a proof-of-concept which tests a good and bad heystack
string to a regex pattern with Poco, Boost and PCRE. I tested it on
two different machines with the following output:
