* gimplify_type_size does not recurse into pointer, record, or function types
(the later are not mentioned).
* the C FE has code to emit fake TYPE_DECLs for pointer types in
c-decl.cc/grokdeclarator
*

Actually, I meant PR84305 for C.

Probably related to PR88256

--- Comment #4 from Martin Uecker ---
The specific problem is triggered by the change to pointer_int_sum in
gcc/c-family/c-common.cc, but the underlying problem is older. The following
example fails since gcc 7:
void f(int n, int

--- Comment #3 from Martin Uecker ---
Smaller example:
void f(int n, int (*a(void))[n])
{
(a())[0];
}
void g(void)
{
int (*a(void))[1];
f(1, a);
}
