Control: tags -1 origin-ubuntu artful ubuntu-patch Hi Sérgio,
I noticed that the hanging builds were building with -O3, which is not considered a correct general-purpose optimization. Switching to -O2 allowed these builds to complete in normal time on all architectures in Ubuntu. You may wish to consider the attached patch for Debian as well. Thanks, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
