I was afraid so.
You could try using the pcre.h header from the embedded pcre in Poco
(apt-get source libPoco-dev, poco-1.3.6p1/Foundation/src/pcre.h), that
I've attached as pocopcre.h and not linking to the system pcre (just g++
regex.cc -lPocoFoundation).
That seems to work for me:
Poco POCO_VERSION on Linux 3.13.0-24-generic @ x86_64
Poco match 1234567890 to pattern ^[0-9]{10} matches? yes
Poco match 123456789 to pattern ^[0-9]{10} matches? no
PCRE 7.8 2008-09-05
PCRE match 1234567890 to pattern ^[0-9]{10} matches? yes
PRCE match 123456789 to pattern ^[0-9]{10} matches? no
If you need a more recent pcre you need to change Poco somehow to not
expose the pcre functions, for example by renaming them, adding a
namespace or using __attribute__ ((visibility ("hidden"))). Maybe the
poco developers can help you with that.

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:
