To repro run
runtime\artifacts\tests\coreclr\windows.x86.Checked\JIT\Performance\JIT.performance\JIT.performance.cmd with

DOTNET_GCStress=0xC
DOTNET_JitStress=2
DOTNET_ReadyToRun=0
DOTNET_TieredCompilation=0

removing DOTNET_JitStress=2 changes the codegen considerably and makes the failure disappear, so it looks like it might be specific to JitStress.

It may be necessary to run the test a few times (3-5 times, maybe more) before seeing the failure. I'd run it in a loop.
Perhaps some uninitialized data is involved, thus nondeterminism.

The actual failing instruction is:

      DOTNET_GCStress=0xC
DOTNET_JitStress=2
DOTNET_ReadyToRun=0
DOTNET_TieredCompilation=0

      removing DOTNET_JitStress=2 changes the codegen considerably and makes the failure disappear, so it looks like it might be specific to JitStress.
      It may be necessary to run the test a few times (3-5 times, maybe more) before seeing the failure. I'd run it in a loop.
      
Perhaps some uninitialized data is involved, thus nondeterminism.

      Since this is in the middle of SIMD instruction sequence, I wonder if this may be related to recent vectorizing optimizations for struct copying/initialization.

        Since this is in the middle of SIMD instruction sequence, I wonder if this may be related to recent vectorizing optimizations for struct copying/initialization.

DOTNET_JitStress=2
DOTNET_ReadyToRun=0
DOTNET_TieredCompilation=0

          removing DOTNET_JitStress=2 changes the codegen considerably and makes the failure disappear, so it looks like it might be specific to JitStress.
          It may be necessary to run the test a few times (3-5 times, maybe more) before seeing the failure. I'd run it in a loop.
          
Perhaps some uninitialized data is involved, thus nondeterminism.

DOTNET_JitStress=2
DOTNET_ReadyToRun=0

            removing DOTNET_JitStress=2 changes the codegen considerably and makes the failure disappear, so it looks like it might be specific to JitStress.
            It may be necessary to run the test a few times (3-5 times, maybe more) before seeing the failure. I'd run it in a loop.
            
Perhaps some uninitialized data is involved, thus nondeterminism.
            The actual failing instruction is:

            Since this is in the middle of SIMD instruction sequence, I wonder if this may be related to recent vectorizing optimizations for struct copying/initialization.

              Since this is in the middle of SIMD instruction sequence, I wonder if this may be related to recent vectorizing optimizations for struct copying/initialization.

DOTNET_ReadyToRun=0
DOTNET_TieredCompilation=0

                removing DOTNET_JitStress=2 changes the codegen considerably and makes the failure disappear, so it looks like it might be specific to JitStress.
                It may be necessary to run the test a few times (3-5 times, maybe more) before seeing the failure. I'd run it in a loop.
                
Perhaps some uninitialized data is involved, thus nondeterminism.
                The actual failing instruction is:
