Summary     : Perl-compatible regular expression library
Description :
PCRE, Perl-compatible regular expression, library has its own native API, but
a set of wrapper functions that are based on the POSIX API are also supplied
in the libpcreposix library. Note that this just provides a POSIX calling
interface to PCRE: the regular expressions themselves still follow Perl syntax
and semantics. This package provides support for strings in 8-bit and UTF-8
encodings. Detailed change log is provided by pcre-doc package.

This release fixes a crash when finding a Unicode property for a character with
a code point greater than 0x10ffff in UTF-32 library while UTF mode is disabled
and JIT mde enabled. It also fixes a buffer overlflow in pcretest tool when
copying a string in UTF-32 mode.
