[Pkg-cups-devel] Bug#668662: /usr/lib/cups/backend/ipp fails with symbol lookup error due to additional hardening flags

[Gaudenz Steinlin]

Package: cups
Version: 1.5.2-10
Severity: important

/usr/lib/cups/backend/ipp fails with:
$ sudo /usr/lib/cups/backend/ipp
/usr/lib/cups/backend/ipp: symbol lookup error:
/usr/lib/cups/backend/ipp: undefined symbol: _ppdCacheGetFinishingValues

I did a quick rebuild with the hardening flag changes from #662821
reverted and that fixes the symbol lookup error. So I guess these flags
should be reconsidered. I did not test if other parts of cups than the
ipp backend are affected as well.
