https://bugs.gentoo.org/415185 http://gcc.gnu.org/ml/gcc-patches/2012-05/msg00555.html From: Alexis Ballier To: gcc-patches@gcc.gnu.org Cc: Alexis Ballier Date: Tue, 8 May 2012 09:53:43 -0400 Subject: [PATCH] gcc/config/freebsd-spec.h: Fix building PIE executables. Link them with crt{begin,end}S.o and Scrt1.o which are PIC instead of crt{begin,end}.o and crt1.o which are not.
