Comment 1 Mike Gilbert gentoo-dev 2017-12-27 15:33:17 UTC
Can you reproduce this without the ricer CFLAGS/LDFLAGS?

If so, please try to figure out which one is causing the failure. My guess is something LTO-related.

LTO was disabled for this build:

"-march=sandybridge -msahf --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=8192" is just the inlining of "-march=native" to play nice with distcc

"-fwrapv" I have no idea where it comes from...

What is so "ricer-y" with my LDFLAGS?
Comment 3 Mike Gilbert gentoo-dev 2017-12-27 16:55:11 UTC
I'm not sure all of the options you have in CFLAGS/LDFLAGS actually work.

Can you reproduce the issue with the following settings?

CFLAGS="-O2 -pipe -march=sandybridge"
LDFLAGS="-Wl,--as-needed"
