Node.js: Abort Signal Memory Fixes and Build Compatibility
Three fixes tighten garbage collection for the Abort Signal any combinator to prevent leaks and missed aborts. Toolchain updates restore builds on new Apple and G-C-C compilers, while smaller runtime and benchmark corrections improve reliability.

Good morning, it's Friday, October 9th, 2026, and here's what's happening in Node dot J-S.
The lead signal today is memory safety for abort handling, with three overlapping fixes to how the Abort Signal any combinator keeps timeout and nested signals alive for garbage collection.
First theme, plugging leaks and missed aborts. One change, in pull request 66617, stops a nested composite from unregistering its parent when the inner signal is collected first, which had left the outer signal stranded in the persistent set. A second, in pull request 66619, moves the already-aborted check earlier…
Second, build compatibility and single-executable reliability. Pull request 66620 updates the Simd JSON library to version 5 point 0 point 3 to fix a compile failure on Apple Clang 17 with exceptions disabled, while also trimming a heavy header include. That pairs with a V-8 cherry-pick for G-C-C 16 on ARM 64 in…
Third, small correctness fixes and more honest measurements. Pull request 66609 rethrows errors from getters on virtual machine contexts instead of swallowing them as undefined, and pull request 66605 stops the test runner from replaying a passing suite when a failing to-do subtest still…
