Since I'm picking up on this bug late, what's the current status?
No progress as I don't understand hardened enough to give support.
I'm seeing a similar bug in non-hardened Gentoo as well on a similar generation CPU: (gdb) run Starting program: /usr/sbin/i7z_GUI warning: Could not load shared library symbols for linux-vdso.so.1.

Update, rebuilding the package without any GCC optimizations does indeed fix my issue as well. Rather than patching, I simply ran: # CFLAGS="-march=native -pipe" CXXFLAGS="-march=native -pipe" emerge i7z
@hardened, any idea here?
*** Bug 551028 has been marked as a duplicate of this bug. ***
(In reply to Justin Lecher from comment #7) > @hardened, any idea here? For me is don't look like a hardened bug more a gcc or a packages bug. As in comment 5 on no hardened.
I encountered this while bumping so I've added a filter-flags call to the ebuild. This application is more power-related than benchmark-related so this isn't a big deal. I'm not on hardened so I don't think that's related either.
are you still hitting this?
