  "message": "[clang][StaticAnalyzer] Reduce MallocSizeofChecker false positives for layout-compatible types (#200253)\n\nWhen one operand is a record type and the other is a non-record type,\ntreat them as compatible if they share the same size and the record\u0027s\nalignment satisfies the scalar\u0027s alignment. This suppresses warnings for\npatterns like `malloc(sizeof(std::atomic\u003cint32_t\u003e))` assigned to an\n`int32_t *` (or a wrapper struct with an identical layout), while still\nflagging genuinely mismatched types such as `long` vs `double` or\nunrelated struct pairs.\n\nrdar://177553628\n\n---------\n\nCo-authored-by: Claude Sonnet 4.6 \u003cnoreply@anthropic.com\u003e",
