Lifting a bnd jmp instruction with x86 architecture results in an IRSB with no instructions and jumpkind Ijk_NoDecode Steps to reproduce the bug
IPython session: In [1]: import pyvex

In [4]: md = capstone.Cs(capstone.CS_ARCH_X86, capstone.CS_MODE_32)
In [5]: bytecode = b'\xf2\xeb\xf5'
In [6]: pyvex.lift(bytecode, 0x0, archinfo.arch_from_id('x86')) Out[6]: IRSB <0x0 bytes, 0 ins., <Arch X86 (LE)>> at 0x0
