webp crashes llvm
clang: /home/ben/cheri/morello-llvm-project/llvm/include/llvm/CodeGen/SelectionDAGNodes.h:897: const llvm::SDValue &llvm::SDNode::getOperand(unsigned int) const: Assertion `Num < NumOperands && "Invalid child # of SDNode!"' failed. PLEASE submit a bug report to https://git.morello-project.org/morello/llvm-project/-/issues and include the crash backtrace, preprocessed source, and associated run script.
I encounter this crash when building OpenCV. There is now a cheribuild target for it but you'll need to re-enable webp to see the crash.
