All six produce their target outputs cleanly today; renamed out of the `issue-*` namespace per CLAUDE.md "Resolving an open issue": | Old | New | |----------------------|-------------------------------------------| | issue-0032 | 181-impl-duplicate-same-file | | issue-0041 | 182-compound-type-in-expression | | issue-0042 | 183-type-alias-size-align | | issue-0044 | 184-objc-defined-class-method-self | | issue-0045 | 185-pack-fn-comptime-return | | issue-0046 | 186-nested-comptime-return | Comment headers tightened to feature-focused (drop the issue-NNNN provenance — that's in git history now). Missing expected `.txt` / `.exit` files captured for 0041 + 0042 (they were untracked because the bugs were fixed silently in adjacent work). `examples/issue-*` after this commit: just `issue-0030.sx` — a feature request (`extern G : T;` cross-file globals) that's never been implemented. Staying in the issue namespace as a parked proposal until the feature lands or gets formally rejected. 220/220 example tests + `zig build test` green.

// Pack-fn (or any comptime-param fn) with a block body containing
|
|
// an explicit `return X;` lowers to clean IR — the inline-return
|
|
// path stores into a dedicated result slot and branches to the
|
|
// shared `ret_done` block instead of emitting a `ret` inside the
|
|
// caller's basic block. Without that, LLVM's verifier rejected the
|
|
// IR with "Terminator found in the middle of a basic block".
|
|
//
|
|
// Surfaced by the variadic heterogeneous type packs feature (step
|
|
// 1 made `..$args` parseable, so the simplest pack-fn smoke test
|
|
// exercised the bug). The root cause is broader than packs: ANY
|
|
// comptime fn with `is_comptime` params, a non-void return, and a
|
|
// block body with `return X;` had the same crash. `format`/`print`
|
|
// use arrow form (`=> expr`) or `#insert`-only bodies, so the bug
|
|
// was invisible until pack-fn bodies surfaced it.
|
|
//
|
|
// Once fixed, calling foo() reaches the body's `return 42;`, the
|
|
// inliner stores 42 into a result slot, the caller loads it as the
|
|
// inline value, and main prints "42".
