source-built ladspa plugin used in ffmpeg segmentation fault

[w4-jihunlorenzopark]

Thank you for your contribution to open such an amazing work.
I built the ladspa from the current master HEAD and am trying to use it by loading in ffmpeg.
It is loaded successful, but got segmentation fault.

I attached the gdb log by your guidance from another issue: #99.

$ gdb --args ffmpeg -loglevel trace -i 01_01_001097_210818_SN_1min_48k_resample.wav -af "ladspa=file=librnnoise_ladspa:plugin=noise_suppressor_mono:controls=50|200|0|0|0" 01_01_001097_210818_SN_1min_rnnoise.wav

Reproducibility

I am using ubuntu 22.04 docker image with i7 cpu which is x86/64. My image was basically built on top of this image #11 (comment) and my only change is replacing the ubuntu version to 22.04. (And additionally, for successful build, I installed libasound2-dev libjack-jackd2-dev libcurl4-openssl-dev libfreetype6-dev libx11-dev libxcomposite-dev libxcursor-dev libxcursor-dev libxext-dev libxinerama-dev libxrandr-dev libxrender-dev libwebkit2gtk-4.0-dev)
My command to trigger segmentation fault was

ffmpeg -loglevel trace -i 01_01_001097_210818_SN_1min_48k_resample.wav -af "ladspa=file=librnnoise_ladspa:plugin=noise_suppressor_mono:controls=50|200|0|0|0" 01_01_001097_210818_SN_1min_rnnoise.wav
