reduced testcase
To make it crash at x86_64-linux, the typedef has to be changed to:
typedef long long ll;
Command line (i686):
$ gcc -O1 -flto -fstrict-aliasing -fgraphite-identity pr44562.c

Another testcase.
I believe I ran into this bug when trying WHOPR bootstrap at -O3 (on
x86_64-linux). I narrowed it down to this piece of preprocessed
source. To reproduce, compile with:
gcc -O3 -g -fuse-linker-plugin -fwhopr -c step2.i
The bug does not occur at -O2.

------- Comment #10 from rguenth at gcc dot gnu dot org 2010-08-25 12:36 -------
So the issue is that when we prime the streamer cache for lto-out we register
the common type nodes (lto_record_common_node) which changes TYPE_CANONICAL
in a way we don't like (it globs int and long int, or long int and long long
int
dependent on whether you are on 32bit or 64bit platforms). This is done
to for example allow mixing of -f[un]signed-char units at link time.
I have a patch.
