Title:
  Segfault (.bss overflow) in PCRE

Status in “pcre3” package in Ubuntu:
  Fix Released
Status in “pcre3” source package in Precise:
  In Progress

Bug description:
  A bug in PCRE was fixed upstream. The issue is a segfault with a
  pattern like /\x{300000}/ui, e.g.

  pcregrep -ui '\x{300000}' < /dev/null

  There was no bounds checking on access to some UCD character tables,
  and insufficient bounds checking in \x character construction. The fix
  was included in a commit that did a lot of other things:

  http://vcs.pcre.org/viewvc?view=revision&revision=774

  but I have split out the relevant single-line fix for your
  convenience. Patch attached.
