20	  architectures built with Clang (all released versions), whereby the stack
21	  frame gets blown up to well over 5k.  This would cause an immediate kernel
22	  panic on most architectures.  We'll revert this when the following bug report
23	  has been resolved: https://github.com/llvm/llvm-project/issues/41896.
