Package: libmath-gsl-perl Version: 0.36-2 It looks like debian/patches/0003-Use-Config-cccdlflags-in-the-build.patch (which was introduced to fix #826009) overwrites ccflags rather than appending to them, removing for instance hardening flags added by debian/patches/0001-Hardening-Build-Patch.patch.
Somewhat unfortunately we only noticed this now, right after upstream merged the patch in 0.39. It would be good to push a fix upstream soonish. I suspect this was just a typo of mine and something like -$ccflags = $Config{cccdlflags} . ' ' . $ldflags; +$ccflags = $Config{cccdlflags} . ' ' . $ccflags; will fix it. -- Niko Tyni nt...@debian.org
