--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
On the FE side, I think this can be fixed with:
--- gcc/cp/init.c.jj    2020-12-09 09:03:38.270054654 +0100
+++ gcc/cp/init.c       2020-12-21 13:05:33.137218177 +0100
@@ -187,7 +187,7 @@ build_zero_init_1 (tree type, tree nelts
   else if (NULLPTR_TYPE_P (type))
     init = build_int_cst (type, 0);
   else if (SCALAR_TYPE_P (type))
-    init = fold (convert (type, integer_zero_node));
+    init = cp_fold_rvalue (convert (type, integer_zero_node));
   else if (RECORD_OR_UNION_CODE_P (TREE_CODE (type)))
     {
       tree field;
It is unclear to me why it uses so arcane way of emitting zero constants, can't
just build_zero_cst (type); do that?, but if it has to, the complex types can't
be handled by simple fold as fold is not recursive, and convert emits
COMPLEX_EXPR with FLOAT_EXPR of 0 operands, so one needs to fold those operands
and only then fold the COMPLEX_EXPR.

I guess there is some bug on the gimplifier side too, it shouldn't ICE even
when such COMPLEX_EXPRs are not simplified.

    gimplify: Gimplify value in gimplify_init_ctor_eval_range [PR98353]

    gimplify_init_ctor_eval_range wasn't gimplifying value, so if it wasn't
    a gimple val, verification at the end of gimplification would ICE (or with
    release checking some random pass later on would ICE or misbehave).

    c++: Fix up floating point complex handling in build_zero_init_1 [PR98353]

    While the gimplifier patch I've just committed fixed an ICE, in some cases
    like on the committed testcase cp folding doesn't happen after
    build_zero_init_1 because it is called already during gimplification.

    For the scalar types, if we want to use convert, the problem with complex
floats
    is that it returns a COMPLEX_EXPR with FLOAT_EXPR arguments which have
    INTEGER_CST 0 as argument.  As fold isn't recursive, it doesn't do anything
    in that case, we need to first fold those FLOAT_EXPRs to REAL_CST 0.0 and
    only afterwards the COMPLEX_EXPR can be folded into COMPLEX_CST with 0.0
    arguments.

    This patch instead just uses build_zero_cst that creates the zero constant
for
    any scalar types (and more) directly, instead of going through multiple
hops.

    gimplify: Gimplify value in gimplify_init_ctor_eval_range [PR98353]

    gimplify_init_ctor_eval_range wasn't gimplifying value, so if it wasn't
    a gimple val, verification at the end of gimplification would ICE (or with
    release checking some random pass later on would ICE or misbehave).
