I can’t see what that disassembles to. Can you tell us what CPU exactly this is for, and which OS and compiler you are using? Do you get any call stacks (for Valgtind itself or the test exe)? Lastly, can you provide a small reproducer? My guess is that somehow you are jumping to a memory location that is not on an instruction boundary. This could be caused by something like stack corruption overwriting a function return address. A+ Paul
