Only with these flags:

./configure CFLAGS='-gdwarf-4 -g3' --with-native-compilation

 do you want I rebuild with what I use previously
+ the flags you provided?

Would be something like this:

./configure CFLAGS='-O8 -gdwarf-4 -g3' --with-native-compilation

system-configuration-options
"'CFLAGS=-gdwarf-4 -g3' --with-native-compilation"
