--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
This is the same ICE as in PR97172:
static void
lto_write_tree (struct output_block *ob, tree expr, bool ref_p)
{
if (!lto_is_streamable (expr))
internal_error ("tree code %qs is not supported in LTO streams",
get_tree_code_name (TREE_CODE (expr)));
and EXPR is BIND_EXPR. It's emitted by the C front end for the VLA parameter
in the definition of
int
qux (int n, int a[(int (*)[n]) { 0 } == 0])
like so:

lto_is_streamable() is defined to return false for BIND_EXPR (and SSA_NAME)
like so:
/* Return true if EXPR is a tree node that can be written to disk. */
static inline bool
lto_is_streamable (tree expr)
{
enum tree_code code = TREE_CODE (expr);
/* Notice that we reject SSA_NAMEs as well. We only emit the SSA
name version in lto_output_tree_ref (see output_ssa_names). */
return !is_lang_specific (expr)
&& code != SSA_NAME
&& code != LANG_TYPE
&& code != MODIFY_EXPR
&& code != INIT_EXPR
&& code != TARGET_EXPR
&& code != BIND_EXPR
&& code != WITH_CLEANUP_EXPR
&& code != STATEMENT_LIST
&& (code == CASE_LABEL_EXPR
|| code == DECL_EXPR
|| TREE_CODE_CLASS (code) != tcc_statement);
}
