Bug 22686 – ICE: dmd segfaults on invalid member reference in static function

Reduced code: ---------- struct S { int[] data; static auto create() { auto self = &this; return { assert(data.length); return self; }; } } ---------- Compiler version: DMD64 D Compiler v2.098.0-430-g8041bcdec Compiler output: ---------- test.d(6): Error: `this` is only defined in non-static member functions, not `create` Segmentation fault ---------- Expected behaviour: compiler should not segfault after rejecting the invalid code that tries to look up a non-static struct member from a static function. This code was reduced from a larger module. I've tried to reduce this code as much as possible, but can't get farther than this. Removing the assert makes the segfault go away. Unwrapping the delegate also makes the segfault go away. The int[] array was reduced from an array of structs, but the array itself can't be removed or changed to a non-array type without making the segfault go away.

The segfault was introduced by https://github.com/dlang/dmd/pull/12595, but the underlying issue is the construction of a `TypeDelegate` from a `TypeErrror`
