dwarf_loader.c: Fixed leaked bogon

[Rakesh Pandit <rakesh.pandit-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

While checking one of big shared objects I found kernel getting
unhappy and sending SIGKILL. File was 282M libwebkit-1.0.so.2.8.1 from
webkit project. (Can be obtained from
http://kojipkgs.fedoraproject.org/packages/webkitgtk/1.1.12/2.fc12/x86_64/webkitgtk-debuginfo-1.1.12-2.fc12.x86_64.rpm
and extracted via rpm2cpio, file is libwebkit-1.0.so.2.8.1.debug)

Subject: [PATCH] dwarf_loader.c: Fixed leaked bogon

Freed chunks of memory left by obstack. It went beyond kernels
expectation for libwebkit-1.0.so.2.debug (from
libwebkit-1.0.so.2.8.1.debug) file and so that it had to send SIGKILL.
