Nightly (`25.0.0.dev257`) tested: crash gone. The extension that reliably SIGSEGVs with 24.0.0 is clean across repeated runs, both import orders. The mechanism is mimalloc ≥ 3.2.6's fixed macOS TLS slots, shared by all co-resident v3 instances with no ownership check (microsoft/mimalloc#1327). 24.0.0's 3.2.7 crashes against a 3.3.1 extension because their heap layouts differ; 25.0.0's 3.3.1 coexists because the layouts happen to match. A pairing where layouts diverge again would re-expose the crash. Bundled ≥ 3.2.6 is the exposure window, which is why 23.0.0 with 3.1.5 was unaffected. -- This is an automated message from the Apache Git Service.
