Sorry for butting in so late, but in Tumbleweed PHP7 seems to build just fine without this patch. Is this really needed? -- You are receiving this mail because: You are on the CC list for the bug.

Yes, it's a proactive patch that will be needed in the near future. We're planning to add -flto as a default $optflags option. Thanks for understanding. -- You are receiving this mail because: You are on the CC list for the bug.

Is this bug fixed in GCC or does php no longer use global register variables? -- You are receiving this mail because: You are on the CC list for the bug.

You are right! I'm not aware of any change at GCC side. So let's try to enable it: https://build.opensuse.org/request/show/784213 -- You are receiving this mail because: You are on the CC list for the bug.
