    OS:   Windows 11 Professional (version: 22H2), build 22621.1702

Code

package bug3

Thing :: struct {
	a: int,
	using B: struct {
		b: uint,
		c: rawptr,
	}
}

main :: proc() {
	things := make_soa(#soa[dynamic]Thing, 1)
	thing := &things[0]
	c := thing.c
}

Current Behavior

Odin\src\llvm_backend_utility.cpp(1064): Assertion Failure: `is_type_pointer(s.type)`

If b and c are swapped places in the struct definition then I get:

Odin\src\llvm_backend_utility.cpp(1138): Panic: TODO(bill): struct_gep type: rawptr, 1
