            Bug ID: 65828
           Summary: [LTO] ICE in streamer_get_builtin_tree, at
                    tree-streamer-in.c:1127
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: steven at uplinklabs dot net

Host architecture is x86_64, GCC version is the 4.9-20150415 snapshot. I've
also seen this ICE on the 5-20150414 snapshot under the same conditions.

The only thing I'm doing that's really unusual is combining -flto and
-fsanitize=undefined.

Normally I'd provide a reduced test case, but delta decided after some churning
that the args file provided to lto1 was already reduced -- and the tarball of
those objects was larger than the max attachment size.

So in lieu of a nice attached repro, here are some steps:

$ wget http://ftp.gnome.org/pub/GNOME/sources/glib/2.44/glib-2.44.0.tar.xz
$ tar xf glib-2.44.0.tar.xz
$ cd glib-2.44.0
$ ./configure --disable-debug CC="gcc -flto" AR="gcc-ar" RANLIB="gcc-ranlib"
CFLAGS="-O2 -fsanitize=undefined"
$ make


It will break on the libglib-2.0.la link step:

$ gcc -v -save-temps -flto -shared  -fPIC -DPIC
