[Discuss-gnuradio] smart pointer problem

[johan kuijpers]

Hi,

I'm fighting a bit with a smart pointer. I want to apply a filter in my 
block. Hence I construct a filter as shown below:

gr_fir_filter_fff_sptr hi_pass = gr_make_fir_filter_fff(1, 
gr_firdes::high_pass (1.0,
                    64000,
                    5000,
                    1000,
                    gr_firdes::WIN_HAMMING,
                    6.76
                ));

as soon as I dereference the smart pointer in order to use the filter I 
get an assertion error: const [with T = gr_block_detail]: Assertion `px 
!= 0' failed.

hi_pass->general_work(noutput_items, ninput_items, input_items, 
output_items);

this means the smart pointer doesn't have a pointer (any longer?) to the 
filter. Does anyone see what I'm doing wrong. I've been trying quite 
hard to find the mistake but I simply don't get it.

Cheers,

John.
