Hello Martin,
I will check my code to find out why it is so big.
Is there an easy way to somehow suppress this warning in case I am
willing to ignore it?
Not without changing the code
(gnuradio-core/src/lib/runtime/gr_buffer.cc). Of course, you can
redirect stderr if you're sure nothing else is going wrong.

I am getting the following warning when running my script:
gr_buffer::allocate_buffer: warning: tried to allocate
4 items of size 88192. Due to alignment requirements
32 were allocated. If this isn't OK, consider padding
your structure to a power-of-two bytes.
On this platform, our allocation granularity is 4096 bytes.
Can somebody tell me how to solve this problem or suppress this warning?
I found it has to do something with fft-size that is not power of 2..
Buffers between blocks are always an integer multiple of the
item-size (in your case 88192) and 4096. The LCM of 88192 and 4096
is pretty large, and tadaa, you get a warning.
It's just a warning. If everything works fine... just ignore it. But
it's a waste of memory. If you want to optimize this, change your
itemsize. You will normally have to adapt the way the data is handled,
e.g., you could pad the input to 90112=22*4096 and then discard
90112-88192=1920 Bytes of every input vector.
Personally, I usually just ignore it, since it rarely turns up in less
unusual applications.
