I think you are using an older standard of C compiler. The C11 does not
allow to initialise a vector using {}. But this doesn't matter as it
compiled successfully. Try initialising the vector with its constructor and
then assign the values. It doesn't make sense but still no harm in trying.

The input signature is not a problem here. For gr::io_signature::*make*(2,
2, sizeof(gr_complex)), i.e. when using make, size of all input items is
same. Its is different when using make2, make3 and makev.
