Reproduce the assertion with the provided PoC using the debug static build and the shown ch options. Start at GlobOptArrays.cpp::GlobOpt::ArraySrcOpt::CheckLoops line 504, then trace the callers through GlobOpt.cpp::OptArraySrc and Func.cpp::TryCodegen. Done means the PoC no longer triggers the landingPadValueType assertion.
