Package: libwebp Severity: important Tags: patch
Libwebp FTBFS on arm64 with a couple of internal compiler errors. I've already filed a bug report on gcc-4.9 ( http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=757738 ) but given that we are currently in the process of pushing arm64 into the official debian archive and given that this package is bootstrap critical it would be appreciated if you would apply the attatched patch to disable optimisation on arm64 and push it into sid.
