src/patches/suse-2.6.27.25/patches.suse/coredump_filter-add-elfhdr-default.patch

   1 From: Jan Blunck <jblunck@suse.de>
   2 Subject: Dump elf headers to core per default
   3
   4 This patch changes the default of /proc/self/coredump_filter to write the elf
   5 header of shared objects and the executable itself to the core file. This
   6 change is necessary to read the build-ids generated by GCC from the produced
   7 core files. These core files might not be readable by anncient versions of
   8 GDB.
