From b3bee76c5f59498b9c189608f0a3132e2013fa1a Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 8 Dec 2023 09:51:34 +0100 Subject: elf: Initialize GLRO(dl_lazy) before relocating libc in dynamic startup GLRO(dl_lazy) is used to set the parameters for the early _dl_relocate_object call, so the consider_profiling setting has to be applied before the call. Fixes commit 78ca44da0160a0b442f0ca1f253e3360f044b2ec ("elf: Relocate libc.so early during startup and dlmopen (bug 31083)").
