-### [Android `.dex`](https://source.android.com/docs/core/runtime/dex-format) bytecode output depends on number of CPU cores
+### Fixed: Android toolchain bug caused the number of CPU cores to affect compiler output
 
-Fay Stegerman [reported a "fun" compiler bug](https://tech.lgbt/@obfusk/113403959098151861) in which:
+Fay Stegerman [wrote](https://tech.lgbt/@obfusk/113403959098151861) that the cause of the [Android toolchain bug from September's report]({{ "/reports/2024-09/#android-toolchain-core-count-issue-reported" | relative_url }}) that she [reported to the Android issue tracker](https://issuetracker.google.com/issues/366412380) has been found and the bug has been fixed.
 
-> the D8 Java to DEX compiler (part of the Android toolchain) eliminated a redundant field load if running the class's static initialiser was known to be free of side effects, which ended up accidentally depending on the sharding of the input, which is dependent on the number of CPU cores used during the build.

-Fay [reported this bug to the Android issue tracker](https://issuetracker.google.com/issues/366412380) but she also made a [small example](https://gist.github.com/obfusk/83822140509dad4148b14bba41adf008) to illustrate when and why this optimisation is valid. This is an update to a bug [previously-reported in these reports]({{ "/reports/2024-09/#android-toolchain-core-count-issue-reported" | relative_url }}).
