segmentation fault if passed invalid data, when ProtocolBuffers::decode is called

[brtriver]

if empty data is passed ...

ProtocolBuffers::decode('Test\Sample', '');

PHP Fatal error:  Uncaught exception 'ProtocolBuffersInvalidProtocolBufferException' with message 'passed variable seems null' in ...

but like this with invalid data ...

ProtocolBuffers::decode('Test\Sample', 1);

[1]    10767 segmentation fault

Is it not supported to throw exception when invalid data is passed now?
