384801: CVE-2006-7230 pcre miscalculation of memory requirements if options are changed during pattern compilation

The MITRE CVE dictionary describes this issue as:

Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate the amount of memory needed for a compiled regular expression pattern when the (1) -x or (2) -i UTF-8 options change within the pattern, which allows context-dependent attackers to cause a denial of service (PCRE or glibc crash) via crafted regular expressions.
