I have the same issue but the commands give me errors. 

The first command gives me this error: sed: can't read ios_binary: No such file or directory

The second command gives me this error: ./minimal/mapping.h(54): _assert(false); errno=2

I had the same issue, i found the solution: you get the “Illegal instruction: 4″ when trying to run within GDB. This is due to old compiled binaries. You can patch the binary with the below command. You have to install sed and ldid(Link Identity Editor).

sed -i'' 's/\x00\x30\x93\xe4/\x00\x30\x93\xe5/g;s/\x00\x30\xd3\xe4/\x00\x30\xd3\xe5/g;' ios_binary

ldid -s ios_binary

I have the same problem, and i tried to just copy the whole command:"sed -i'' 's/\x00\x30\x93\xe4/\x00\x30\x93\xe5/g;s/\x00\x30\xd3\xe4/\x00\x30\xd3\xe5/g;' ios_binary

ldid -s ios_binary" but it didn't worked...Im a completely noob with all this stuff
