@BradleyWood, may I ask you to take a look at this? Looking at this in windbg, the illegal instruction is this:

282a0e27 62f17e086f8cf208000000 vmovdqu32 xmm1, xmmword ptr [edx+esi*8+8

[BradleyWood]

The encoding of that instruction is valid, but it is not supported on 32-bit. Not sure how it got generated.

[BradleyWood]

I suppose we have an AVX-512 capable machine running a WIN-32 build which is why it was generated.

[pshipton]

Is this a recent regression?

[BradleyWood]

Is this a recent regression?

I think it was probably introduced around a year and a half ago

[pshipton]

Seems it doesn't need to be fixed in 0.44 then.

[pshipton]

I'll close this as a dup of #19408 even though this was opened first.
