// issue 0155 — indexing a pointer-to-scalar (`pc[0]` where `pc: *i64`) panics
// the compiler at LLVM emission instead of either lowering `pc[i]` like C
// (`*(pc + i)`) or emitting a clean diagnostic that `*T` is not indexable.
//
// Observed: `thread … panic: unresolved type reached LLVM emission`
//           at src/backend/llvm/types.zig:196 (the `.unresolved` arm of
//           toLLVMTypeInfo), reached via emitIndexGet
//           (src/backend/llvm/ops.zig ~1988) → the index expression's element
//           type resolves to `.unresolved` and is never diagnosed.
// Expected: either a working scalar-pointer index (`pc[0]` == `pc.*`) or a
//           proper "cannot index a *T; use a slice / deref with .*" diagnostic.
//           A `.unresolved` reaching LLVM is always a compiler bug.
