gdb <value optimized out>

I never used -g3 and still got enough information, I'm also a gentoo user but 
use -ggdb, also if the value you're looking for is in some external library 
you might want to add -ggdb to your CFLAGS and rebuild the library, probably 
using FEATURES="splitdebug" not to pollute your system with that info.

Best regards
