Copilot got stuck in an infinite text loop

[mlh758]

Type: Bug

I asked:

"Is there a AVX512 SIMD instruction that would allow you to reverse the digits of an integer with a single instruction?"

Followed by:

"What instructions would I need to extract digits from a number with x86 assembler?"

I recognize these were stupid questions, don't judge me.

And it started constantly emitting:
mov edx, dword edx
mov edx, [edx]
mov edx, dword edx
mov edx, [edx]
mov edx, dword edx
mov edx, [edx]
mov edx, dword edx
mov edx, [edx]
mov edx, dword edx
mov edx, [edx]
mov edx, dword edx
mov edx, [edx]
mov edx, dword edx
mov edx, [edx]
mov edx, dword
