In Ubuntu 14.04, libPocoFoundation.so has some global variables of pcre. I found the executable which links both libPocoFoundation.so and libpcre.so outputs wrong results by pcre functions.
nm -D --defined-only /usr/lib/libPocoFoundation.so | grep pcre 0000000000110800 R _pcre_OP_lengths 000000000010f2a0 R _pcre_ucd_records 000000000010d0a0 R _pcre_ucd_stage1 00000000001032a0 R _pcre_ucd_stage2 00000000001106e0 R _pcre_ucp_gentype 00000000001107e0 R _pcre_utf8_table1 00000000001107d8 R _pcre_utf8_table1_size 00000000001107c0 R _pcre_utf8_table2 00000000001107a0 R _pcre_utf8_table3 0000000000110760 R _pcre_utf8_table4 0000000000110120 R _pcre_utt 00000000001103e0 R _pcre_utt_names 0000000000110100 R _pcre_utt_size -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pcre3 in Ubuntu. https://bugs.launchpad.net/bugs/1361610 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.
