showwavespic with replace ends up with SIGSEGV

[KE]

Summary of the bug:

When generating IMAGE out of WAV, when setting replace=1, ffmpeg exists with code 139 and terminated by signal SIGSEGV (Address boundary error)

Without replace=1 for showwavespic filter, the png is generated without issues.

How to reproduce:

% ffmpeg -hide_banner -nostats -y -v warning -f s16le -i audio.wav -filter_complex aformat=channel_layouts=mono,showwavespic=s=600x90:colors=#bfbfbf,drawbox=x=0:y=ih/2:w=iw:h=1:replace=1:t=1:color=#bfbfbf -frames:v 1 audio.png
