This is because Phase 4 fixes (especially the RC1 +DOM/HTML fix) exposed many more subtests in previously-passing tests, causing them to +reach new code paths that crash on pre-existing issues (DESTROY not implemented, +`Unknown encoding 'Latin-1'`, `Can't write to file ""`, indirect method parsing). +Tests like request.t (41/41), path.t (15/15), log.t (8/8), reactor_poll.t (7/7), +commands.t (37/37), and renderer.t (8/8) pass ALL subtests but exit 255 due to +crashes after the last subtest. + +#### Phase 4 fixes applied + +1. **RC1 - Mojo::DOM HTML parsing / CSS selectors** (RuntimeRegex.java): + Fix zero-length `/gc` match semantics. After a zero-length match, Perl retries + at the SAME position with NOTEMPTY constraint before falling back to bumpalong. + Added `notemptyPattern` variant that prepends `(?=[\s\S])` and converts `??` to `?`. + This fixed Mojo::DOM::HTML `$TOKEN_RE` and CSS `>` child combinator. + **dom.t: 1/2 -> 107/108** (+106 subtests). + +2. **RC5 - IO::Compress::Gzip** (TieOperators.java): + Remove `tiedDestroy()` calls from `untie()`. In Perl, DESTROY is only called + during garbage collection, not during untie. The previous behavior caused + IO::Compress::Base::DESTROY to fire prematurely, clearing glob hash entries + before `close()` finished writing trailers. Gzip compression now works. + +3. **RC6 - `re::regexp_pattern()`** (Re.java): + Implement `re::regexp_pattern()` which extracts pattern string and modifiers + from a compiled regex. Returns `(pattern, modifiers)` in list context, + `(?flags:pattern)` in scalar context. + +#### Key subtest improvements from Phase 4 + +| Test | Phase 3 | Phase 4 | Change | +|------|---------|---------|--------| +| dom.t | 1/2 | 107/108 | **+106** | +| response.t | 28/29 | 49/52 | +21 | +| request.t | 31/33 | 41/41 | +10 | +| restful_lite_app.t | 41/91 | 90/91 | **+49** | +| tag_helper_lite_app.t | 78/90 | 86/90 | +8 | +| production_app.t | 71/95 | 52/60 | (fewer subtests run) | +| bytestream.t | 30/31 | 31/32 | +1 | +| lite_app.t | 298/302 | 298/302 | (stable) | + +#### Tests that pass all subtests but crash (exit 255) + +These tests pass every subtest but die after the last one due to pre-existing issues +(DESTROY cleanup, encoding errors, indirect method parsing).
