Confirmed. I will have a look.

(In reply to Richard Biener from comment #2)
> Confirmed. I will have a look.
It's interesting since the cost model needs to be disabled to reproduce it.
It looks like when it is one of the load nodes already has a VEC_STMT so the
assert crashed in schedule_slp_node
vec_stmts = {
m_vec = 0x4e0e870
},
>>> dbgrep (node)
# VUSE <.MEM_6(D)>
_14 = REALPART_EXPR <*tfn_7(D)>;
If that helps.

tree-optimization/99924 - visit permute nodes again when partitioning
Since SLP graph partitioning works on scalar stmts (because it's done
for costing) we have to make sure to visit permute nodes multiple
times since they will not pull partitions together.
2021-04-06 Richard Biener <rguenther@suse.de>
PR tree-optimization/99924
* tree-vect-slp.c (vect_bb_partition_graph_r): Do not mark
nodes w/o scalar stmts as visited.
* gfortran.dg/vect/pr99924.f90: New testcase.
