--- Comment #4 from christophe.lyon at st dot com ---
Since commit 211625:
2014-06-13  Richard Biener  <rguenther@suse.de>

        * tree-ssa-pre.c (eliminate_dom_walker::before_dom_children):
        Rewrite to propagate the VN result into all uses where
        possible and to remove stmts becoming dead because of that.
        (eliminate): Generalize stmt removal handling, remove in
        reverse dominator order to support proper debug stmt
        generation.  Update stmts before removing stmts.
        * tree-ssa-propagate.c (propagate_tree_value): Remove
        bogus assert.

The same error now appears when building other GCC configurations:
--target                   mode --with-cpu      --with-fpu
arm-none-linux-gnueabi        arm     cortex-a9     default
arm-none-linux-gnueabihf   arm     cortex-a9     neon-fp16
arm-none-linux-gnueabihf   arm     cortex-a9     vfp
arm-none-linux-gnueabihf   arm     cortex-a15     neon-vfpv4
armeb-none-linux-gnueabihf arm     cortex-a9     neon-fp16

Vladimir, can you have a look?
