How to reproduce:

Create a new empty 3D project
Navigate to File -> Build Profiles and switch the platform to Android
Navigate to Edit -> Project Settings -> Player -> Other Settings
Set Scripting Backend to “IL2CPP” and Target Architectures to “ARM64”
Build the project to generate an APK
Extract the built APK (e.g., rename to .zip and unzip) and navigate into the lib/arm64-v8a/ folder to locate the core shared libraries (such as libmain.so, libil2cpp.so, libunity.so, libc++_shared.so, libgame.so)
Open a terminal directly in that lib/arm64-v8a/ folder and run this command using the path from your Unity installation: “[UnityInstallPath]/PlaybackEngines/AndroidPlayer/NDK/toolchains/llvm/prebuilt/darwin-x86_64/bin/llvm-readelf -W -l <library_name>.so”
Observe the GNU_RELRO row in “Program Headers” output

Actual result: The sum of the VirtAddr and MemSiz values from the GNU_RELRO row does not divide perfectly by 0x4000 (leaves a remainder), failing the Android 16-KB alignment check
Expected result: The sum of the VirtAddr and MemSiz values from the GNU_RELRO row divides perfectly by 0x4000 (zero remainder) to correctly align for Android 16-KB page sizes

Reproducible with: 6000.0.38f1, 6000.0.85f1, 6000.3.26f1, 6000.6.5f1, 6000.7.0b4, 7000.0.0a8
Could not test with: 6000.0.0f1 (16-KB page size support was added in version 6000.0.38f1)

Reproducible on: Windows 10 (by user), MacOS 26.7.1 (M3 Max)
Not reproducible on: No other environments tested

Note: The bug behaves differently across different versions. In 6000.0.x, 6000.3.x, and 6000.6.x: “libmain.so” fail the GNU_RELRO 16-KB alignment. In 6000.7.0b4: “libunity.so” aligns perfectly, but “libil2cpp.so” fails. In 7000.0.0a8: “libil2cpp.so” aligns perfectly, but “libunity.so” fails
