Subject: pcre 8.33 changes restorecon behavior

Hi guys

Since libpcre 8.33, the behavior of restorecon is different. Take the
context for /sbin for instance:

Before libpcre 8.33:
  # matchpathcon /sbin
  /sbin	system_u:object_r:bin_t:s0

With and after libpcre 8.33:
  # matchpathcon /sbin
  /sbin	<<none>>

As a result, trying to reset the label fails:

# restorecon -Fv /sbin
restorecon:  Warning no default label for /sbin

Is this a bug in libpcre or are we using it differently? According to
Alphat-PC, it is due to rev 1313 of libpcre:
http://vcs.pcre.org/viewvc?view=revision&revision=1313

Thanks to Alphat-PC for reporting and debugging it at
https://bugs.gentoo.org/show_bug.cgi?id=471718

Wkr,
	Sven Vermeulen
