Description Ettore Di Giacinto (RETIRED) gentoo-dev 2016-08-23 21:49:19 UTC 
emerge --info: http://pastebin.com/YLy4Dzjv

The ebuilds hardcodes optimize=native in myesconsargs, 
this results in produced tbz2 not usable in other system with different CPUs.

optimize=0 fixes the problem, for Sabayon we had to fork the ebuild: https://github.com/Sabayon/for-gentoo/commit/37cf3f6978d7c1dfdb09838f9012e79bcf792860#diff-44084ddbe259d14e0ff70b69aafdb17fR104

Reproducible: Always

Steps to Reproduce:
1. emerge -B mixxx from a system 
2. use the produced tbz2 with a different system with a different CPU from the one that compiled it
3. run mixxx --help
Actual Results:  
mixxx returns 'Illegal Instruction'

Expected Results:  
mixxx usage output
