This looks like a runtime issue to me. This assert is failing:
https://github.com/dotnet/coreclr/blob/47a155800eecb965e7f49e19f6109e93f370716c/src/System.Private.CoreLib/shared/System/Collections/Generic/ArraySortHelper.cs#L367
presumably because this call:
https://github.com/dotnet/coreclr/blob/47a155800eecb965e7f49e19f6109e93f370716c/src/System.Private.CoreLib/shared/System/Collections/Generic/List.cs#L285
passed in a null _items. But _items should never be null: every ctor initializes it to a non-null array, and it's then never assigned to anything but a non-null array. That suggests to me that there's some kind of corruption / codegen issue / etc. causing the parameter to be read as null. But maybe I'm missing something.

[jeffschwMSFT]

Good point, I missed that this was a jitstress mode.

[BruceForstall]

This run was:

COMPlus_JitStress=1
COMPlus_TieredCompilation=1

[BruceForstall]

@sandreenko Can you investigate this? (and the related issues)

[sandreenko]

WIll do.

[sandreenko]

Can be repro with:
COMPlus_JitStress=1

when running the single method:
-method System.Collections.Immutable.Tests.ImmutableListTest.BinarySearchPartialSortedList -parallel none

Also, a few time I saw an invalid GCRef asserts in VM, will try to catch them as well.

[sandreenko]

a stable repro settings:

COMPlus_ContinueOnAssert=0
COMPlus_JitNoInline=1
complus_JitStressModeNames=STRESS_TAILCALL
complus_JitStressModeNamesOnly=1
complus_jitstressrange=3826701918-3826701918
COMPlus_NoGuiOnAssert=0
COMPlus_ReadyToRun=0
complus_TieredCompilation=0
COMPlus_ZapDisable=1

I added a small repro test for this bug. The bug is complex and is caused by code path that would be replaced soon by @jakobbotsch, so we have decided not to fix that in the old implementation of slow tail calls via helpers.

In short TailCallCopyArgsThunk can't restore register arguments for the tail call in this case because it has a shifted pointer to the arg array on the stack (shift is 0x10),
so when jihelpers.cpp:JIT_TailCall calls INVOKE_COPY_ARGS_HELPER(copyArgs, args, &ctx, (DWORD_PTR*)pbTempStackFill, cbArgArea); ctx doesn't get valid values for the arguments.

It happens because in this case have additional arguments that are not checked correctly.

That is how the call looks like with a tail call prefix:

                                                              /--*  t268   ref    this in rcx
