How to remove/suppress gr_buffer::allocate_buffer: warning:

GNU Radio
1

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…

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.

It’s just a warning. If everything works fine… just ignore it. But
