Hi: Why I run the benchmark_ofdm and there is a warning like below? gr_buffer::allocate_buffer: warning: tried to allocate 20 items of size 1600. Due to alignment requirements 64 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. And, the program stops!
Does anyone knows what do I miss? Thanks!!
