Confirmed.  We're in

4318    static inline void
4319    free_lang_data_in_one_sizepos (tree *expr_p)
4320    {
4321      tree expr = *expr_p;
4322      if (CONTAINS_PLACEHOLDER_P (expr))
4323        *expr_p = build0 (PLACEHOLDER_EXPR, TREE_TYPE (expr));
4324    }

for

    arg 1 <integer_cst 0x7ffff7efc000 type <integer_type 0x7ffff7ee9498 int>

which is the max-value of

 <integer_type 0x7ffff5b90a80
    type <integer_type 0x7ffff7ee9000 long unsigned int public unsigned
sizetype DI
        size <integer_cst 0x7ffff7ed37a8 constant 64>

    align 64 symtab 0 alias set -1 structural equality precision 64 min
<integer_cst 0x7ffff7ed3410 0> max <minus_expr 0x7ffff7ff91f8>>

which is in TYPE_DOMAIN of an array-type of a field-decl of DDQMC which
is the type of an IDENTIFIER_NODE.

I have a patch.
