I cannot reproduce this :/
Have you tried to rebuild it with CFLAGS="-O2 -pipe" only?
(In reply to comment #3) > Have you tried to rebuild it with CFLAGS="-O2 -pipe" only? That solved it. Thanks! Teun
This is a bug in gcc then, as it is using unproper CFLAGS when using "native", reassigning as gcc maintainers will know better how to handle problems like this
No, it just means it's getting triggered by some target-specific optimization. It's still gnome-nettool that needs fixing. What does `echo "" | gcc -march=native -v -E - 2>&1 | grep cc1` say?
