With the SPIR-V shader attached to this bug, running spirv-opt with a loop unroll pass generates invalid spir-v that fails spirv-val:

> spirv-opt --version
SPIRV-Tools v2024.2 v2019.1-2077-g65d30c31

> spirv-opt --loop-unroll test.spv -o opt.spv

Produces a shader that fails spirv-val:

> spirv-val opt.spv
error: line 415: ID '23262[%23262]' has not been defined
  %25204 = OpULessThan %bool %23262 %uint_4
