For me the nightly build of CP2K now fails with /data/vjoost/gnu/cp2k/cp2k/makefiles/../src/pw_spline_utils.F:2303:0: SUBROUTINE add_fine2coarse(fine_values_pw,coarse_coeffs_pw,& internal compiler error: Segmentation fault 0xb525df crash_signal ../../gcc/gcc/toplev.c:336 0x1322c4c dr_misalignment ../../gcc/gcc/tree-vectorizer.h:889 0x1322c4c aligned_access_p ../../gcc/gcc/tree-vectorizer.h:902 0x1322c4c vect_supportable_dr_alignment(data_reference*, bool) ../../gcc/gcc/tree-vect-data-refs.c:5863 0xd96d9f vectorizable_load ../../gcc/gcc/tree-vect-stmts.c:6706 0xda061d vect_transform_stmt(gimple*, gimple_stmt_iterator*, bool*, _slp_tree*, _slp_instance*) ../../gcc/gcc/tree-vect-stmts.c:7998 0xdc0a31 vect_schedule_slp_instance ../../gcc/gcc/tree-vect-slp.c:3468 not sure if it is related.
