The assert is just a bit overzealous.
(gdb) p debug_bb ($2)
<bb 47> [local count: 708959595]:
# prephitmp_152 = PHI <_276(45), pretmp_2(46)>
# prephitmp_205 = PHI <_85(45), pretmp_341(46)>
# prephitmp_556 = PHI <_86(45), pretmp_298(46)>
# prephitmp_353 = PHI <_275(45), pretmp_555(46)>
result_282 = (void *) prephitmp_152;
_283 = prephitmp_152 + 8;
MEM[(struct Zone *)_86].position_ = _283;
vectp.1975_450 = result_282;
MEM <vector(2) int> [(int *)vectp.1975_450] = { 0, 0 };
use_stmt is the last stmt so code is SSA_NAME. But it's also an odd SLP graph
as we have two graphs we vectorize separately where parts of one graph
are used in address computes of another (the addresses we don't model in SLP
so we "fail" to merge the SLP graphs).
Going to be interesting to see whether a reduced testcase reproduces that.
Anyway, the easiest "fix" is to simply remove the assert. The assert is
not technically necessary, it's just there trying to "prove" we understand
the situations this hack is necessary (I don't think we do ;)).

From a quick look it still has the odd property I observed.

Yep, I decided to backport the assert -> checking-assert change. There's
no "good" way to handle the case we are running into. On the branch we
run into an ADDR_EXPR.
As said with the original patch to trunk an option would be to remove the
assert alltogether, but not sure how important that would be. It's still
interesting to see other cases we run into with this "FIXME" code path
(but as said, there's no good way to capture this particular case within
the assert).
