Subject: [PATCH] Don't try to free rpath strings allocated during startup
Date: Mon, 13 Sep 2010 07:41:00 -0000 [thread overview]
Message-ID: <m34oduqedt.fsf@hase.home> (raw)
The stub malloc from dl-minimal.c is used during all of startup until
ld.so is re-relocated, so the rpath string allocated so far cannot be
freed in the freeres routine.
Andreas.

re-relocationg ld.so.
