Summary	0006498: LV2 Plugin Analysis exceeds maxBlockLength overflowing plugin buffers
Description	LV2 plugins can check the host features for the maximum block size they will ever need to process. The rkrlv2 plugins allocate several buffers that will only match this block size. The reported max size seems to match the JACK settings block size (e.g. 256), but when the analysis window is opened, it requests a block of 4096 samples be processed. This causes a segfault as the buffers overflow. Use rkr Distband as an example.
