From 0f55d28a4d1f425343eb5aeae3eb7ffb3efd266a Mon Sep 17 00:00:00 2001 From: Qing He Date: Sat, 25 Sep 2010 15:19:45 +0800 Subject: glibc & eglibc: fix mips DT_MIPS_RLD_MAP checking On mips target, binutils currently sets DT_MIPS_RLD_MAP to 0 in dynamic section if a --version-script sets _RLD_MAP to local. This is apparently a binutils bug, but libc shouldn't segfault in this case. Add sanity check on the entry to avoid segfault, fixes [BUGID #287].
