I confirm that I tested the exact same change on arm64, on both native and cross-compiled build and that it fixes the issue I reported. > [ Risks ] > The upstream commit zero-initializes memory which previous was not > initialized after allocation, and might have contained garbage values > which were used. The fix is isolated as a oneliner. I agree that the risk is quite low. The fix also likely improves reproducibility by removing a dependence on build time random data which is always good think.
