Hi,
You shouldn't have used "hardened" unless you running a hardened system.
Could be done via (hardened + pic IIRC) using normal system profile or
w/o any special USE-flags, when using a "hardened" profile.
Check the output of: gcc-config -l (what profile is GCC using) and
switch to vanilla. Hope your toolchain isn't recompiled too.
IIRC 'hardened-php' isn't part of a real "hardened" system (you must be
using a hardened kernel too - hardened|selinux|rsbac-sources) it's only
a hardening patch for PHP.
