Comment (by Jesús Leganés-Combarro):

 https://johnvansickle.com/ffmpeg/release-readme.txt

 otes:  A limitation of statically linking glibc is the loss of DNS
 resolution. Installing
              nscd through your package manager will fix this.

 So, after installing `nscd` package (sudo apt install nscd), static build
 is not crashing anymore :-( It seems to me "maybe" when ffmpeg does a DNS
 resolution, it's being returned an unmanaged value (probably a null
 pointer?) and that's why the crash and core dump is being generated. Does
 it makes sense?
