[ci-scan] Build break: NativeAOT linker alignment error in PhysicalPromotion test (arm64)

[github-actions]

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1484197
Build error leg or test failing: linux-arm64 Checked NativeAOT_Pri1 - JIT/Directed/Directed_3.csproj

Error Details

NativeAOT test build fails on linux-arm64 with a linker alignment error in the mixedpromotion_PhysicalPromotion__FromOldToPhysicalMismatched function. The linker (ld.lld) reports an improper alignment for relocation R_AARCH64_LDST64_ABS_LO12_NC. This prevents the entire NativeAOT_Pri1 test leg from running on linux-arm64.

ld.lld : error : Directed_3.o:(function mixedpromotion_PhysicalPromotion__FromOldToPhysicalMismatched: __managedcode+0x1c1530): improper alignment for relocation R_AARCH64_LDST64_ABS_LO12_NC: 0x74A52C is not aligned to 8 bytes [src/tests/JIT/Directed/Directed_3.csproj]
clang-22 : error : linker command failed with exit code 1 (use -v to see invocation) [src/tests/JIT/Directed/Directed_3.csproj]
