Rename all example tests/companions to the XXXX-category-test-name scheme (per-category 100-blocks: basic 0010, types 0100, ... errors 1000, diagnostics 1100, ffi 1200, ffi-objc 1300, ffi-jni 1400, vectors 1500, platform 1600). Companions and dir/C fixtures move in lockstep with their parent test; #import/#source/#include paths rewritten to match. Expected output now lives in examples/expected/ (a sibling dir of the tests) split into three streams per the new convention: <name>.exit / <name>.stdout / <name>.stderr (+ optional <name>.ir) run_examples.sh rewritten: scans examples/ and issues/ for an expected/<name>.exit marker, captures stdout and stderr separately (no more 2>&1), compares each stream + exit + optional IR snapshot. Behavior validated unchanged: every renamed test reproduces its prior merged output + exit (diffs limited to file paths/basenames embedded in diagnostics + traces, which correctly reflect the new names). Suite: 292 passed, 0 failed. 50-smoke.sx split + issue relocation + docs follow in subsequent commits.

// ffi-objc-arc-00b — multi-instance allocator threading.
|
|
//
|
|
// Verifies that EACH sx-defined-class instance captures its own
|
|
// allocator and round-trips through it. Catches bugs where:
|
|
// - the captured allocator is shared across instances (one global
|
|
// slot instead of per-instance).
|
|
// - alloc captures the wrong allocator on the 2nd+ instance.
|
|
// - dealloc reads garbage if state[0] is overwritten between
|
|
// instances.
|
|
//
|
|
// Three instances → three alloc events → three dealloc events. The
|
|
// tracker observes exactly +3 / +3 deltas.
