llvm-mc: /home/jyyou/src/llvm-trunk/lib/Target/ARM/Disassembler/ARMDisassemblerCore.cpp:1241: bool DisassembleLdStMulFrm(llvm::MCInst&, unsigned int, uint32_t, short unsigned int, unsigned int&, llvm::ARMBasicMCBuilder*): Assertion `NumOps >= 5 && "LdStMulFrm expects NumOps >= 5"' failed.
================
It works fine while changing NumOps >= 5 into NumOps >= 4.
