ffmpeg: malloc_consolidate(): invalid chunk size

[dorukayhan]

I tried to run /esmcaption caption: bind p "say сука блять" on this image and FFmpeg exploded as such:

Trying it again resulted in the same error. /caption caption: bind p "say сука блять", however, worked just fine. I could also shrink the image (/resize width: 249 height: -1) and then /esmcaption the shrunk image (/esmcaption caption: bind p "say сука блять") (which resulted in an ugly caption but that's probably an unrelated font problem).

What gives?
