iOS next 4-byte alignment causes a crash problem

Staticvoid teacore (unsignedint in[2], unsignedint out[2], unsignedint key[4], long rounds)

//arm Memory 4- byte alignment

The iOS platform requires memory byte alignment when forcing data type conversions. And the debug environment is not required. If the two coercion type conversion is separated by the OC code, release execution is also correct, so again it is suspected that the compiler optimization is the result of XOCDE at compile time.
