Fact is, from my experience(s), valgrind is literal sh!t as it does not 
produce the output you are requesting. I doubt I am the only one 
experiencing these frequent awful crashes, especially during multimedia, 
i.e., video playback. There is something inherently irrationally coded 
either in latest EFL and/or Enlightenment (included in Debian Trixie, 
aka, 'testing'.

During compiling of some larger programs, I have read the logs where 
they utilize 'asan' as some sort of built-in testing framework prior to 
producing their binaries. EFL/Enlightenment might benefit from such 
'asan' integration prior to spitting out their binaries. Of course, that 
may be too much for a single developer working on such a complex 
project. Yet, producing beta quality releases which will compete with 
other more established, with a larger pool of developers, window 
managers leaves much to be desired.

As a matter of fact, in Debian, MPV is tied to Pipewire which has 
dependencies on GNOME; notwithstanding, I had to rebuild MPV, but in 
order to do that I had to build FFMPEG, removing its dependencies 
Pipewire/GNOME in order not to bring in the GNOME bloat into 
Enlightenment. Yet playing video, either streams and/or local, produces 
frequent unexpected crashes. And this happens also, as I mentioned 
before, while using latest Firefox/Chrome and going to YouTube site and 
playing videos.
