Added this to PR so we can consider the potential change. This would've caught the issue in CI.

The Apple Silicon build is currently running on macos-13 which is (1) Intel and (2) soon to be deprecated in a month. Is there any reason Apple Silicon was built on an Intel runner?

Changed to macos-26 just because it's the latest (and matches the environment where I found this issue!) but it's currently marked as "public preview" in GH docs. It should still be a good idea to update this at least to macos-14 due to the deprecation (macos-15 being the latest non-preview runner) and to build natively on Apple Silicon. macos-15 is also the minimum runner that has Clang 16 which would have caught this issue in CI.

Also note that the macos-x86-64 job is also using macos-13 and should probably be updated to macos-15-intel (which will also be deprecated in GH by Aug 2027) or cross-compile from an Apple Silicon runner.

Additionally: right below these lines there's...

CXXFLAGS: -target arm64-apple-macos11

I guess it was there because it was cross-compiling from Intel to Apple Silicon, but I still didn't touch it because that 11 makes me think there are breaking changes for binaries built targetting different MacOS versions?

Also note that the macos-x86-64 job is not specifying any CXXFLAGS so it might need a change to keep the target stable if macos-13 runner is changed.
