Title:
  libPCRE3 8.31 regex matching is not working

Status in pcre3 package in Ubuntu:
  Confirmed
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:

  Poco  match 1234567890 to pattern ^[0-9]{10} matches? no --> NOT CORRECT
  Poco  match 123456789 to pattern ^[0-9]{10} matches? no
