Fixed In Version: pcre-8.32-15.el7 Doc Type: Bug Fix
Doc Text:
An error in first character optimization was causing PCRE to incorrectly evaluate regular expressions where a start-anchored character with more than once case follows circumflex in multi-line UTF-8 mode. This update resolves the problem and PCRE now properly evaluates these regular expressions.
