gcc uses new methods for handling PIC code, for example a thunk loading the value in %ecx and a new %ebx thunk not conflicting with the i686 define and with different declarations (see bug 518210 for an example). The doc is at http://wiki.gentoo.org/wiki/Hardened/HOWTO_locate_and_fix_textrels

Reproducible: Always
