From 5f4e5dd4ddcff9b6f7a87fd940d3e23ed3c543bd Mon Sep 17 00:00:00 2001 From: Alex Garcia Date: Fri, 13 Mar 2026 11:46:11 -0700 Subject: [PATCH] fuzz-macos: mark as continue-on-error (best-effort) Homebrew LLVM 18 runtime dylibs use typed allocation ABI symbols (__ZnwmSt19__type_descriptor_t) not available in macOS 14's system libc++, causing dyld to abort. Xcode clang doesn't ship libFuzzer. Mark fuzz-macos as continue-on-error (same as fuzz-windows) so it doesn't block CI. Linux fuzzing remains the primary bug detector.
