If test.bin is an executable, you can’t just run it like that - executables have plenty of metadata describing how they’re loaded into memory

In this case, you’re probably hitting the \x7FELF ahead (which decides as jg 0x47), jumping into the middle of a size field, which doesn’t decode as a valid instruction, and crashing

You should debug then (although I’m fairly sure that command copies objects, not code)
