Beyond the above, IIRC Android ships with integer overflow enabled (but can't find where I read this).

  You can confirm it by looking into the source code: https://android.googlesource.com/platform/build/soong/+/refs/heads/android13-release/rust/config/global.go#49 https://android.googlesource.com/platform/build/soong/+/refs... Not an expert, but a file named "global.go" makes me confident :).

    Amusing to see that the compiler flags for Rust are stored in a Go file ;)

  Not that it's important, but just a note that unless you recompile the standard library yourself, integer overflow will still be off for that code since it ships compiled. (Correct me if I'm wrong, that's my recollection).

    The Android project compiles the standard library themselves: https://android.googlesource.com/platform/prebuilts/rust/+/android13-release/Android.bp https://android.googlesource.com/platform/prebuilts/rust/+/a...
