Latest LibreElec testbuild crashes when playing video

[peno64]

I report this bug here on recommendation of @popcornmix

Describe the bug
When playing a video with the latest LibreElec 19 testbuilds, suddenly a crash appears and kodi restarts. This does not happen always and at random moments. However it happens often enough to reproduce.

To reproduce
Create a brand new fresh install of libreelec kodi 18.5 and then update with the latest libreelec 19 testbuild. I used #104, 04-Jan-2020 on a rpi3
Play a movie and the crash occurs after some time. Sometimes a second try must be done.

Expected behaviour
No crash should happen

Actual behaviour
It crashes
The crahlog file contains:

Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x76f224d0 in memcpy () from /usr/lib/libarmmem-v7l.so

System
the raspinfo command does not exist on my system

• Which model of Raspberry Pi? Pi3B+

• Which OS and version (cat /etc/rpi-issue)? cat /etc/rpi-issue gives no such file or directory...

  Linux LibreELEC 5.4.7 kernel_emergency usage with latest firmware binaries (18th April) #3 SMP Sat Jan 4 21:03:00 GMT 2020 armv7l GNU/Linux

Logs
I include the crashlog file here: https://paste.kodi.tv/xajacecuda.kodi
This crashlog also includes the kodi.log at that moment.

Additional context
I have a complete image available from this setup. So you can restore the image on a micro sd card (min 8 gb) and boot with it and then goto video and play the video there.
Please provide me an email address to whom I can send a link of this image.
If you prefer the movie only I can also provide it. It is a movie I recorded myself. I prefer not to post these links here publically but if really needed I will do.

Ping @6by9 This crash seems to be caused by raspberrypi/userland#586

LE image played video (72m) without crashing.
I'll try leaving it looping overnight.
I'll also try with a raspbian kodi build with debug enabled which will hopefully fail in the same way on this video file (and provide more information when it crashes).

We reverted the suspected commit a few days ago (10 Jan). It should be in last few Milhouse nightly builds. Can you confirm if the issue is resolved.

@popcornmix
ok, trying with #113, 13-Jan-2020 on a pi3. Will play movies all night long to see if it is ok.
Thank you

Playing already 22 hours of movies without interruption and all goes well...

[peno64]

Played 24 hours extra and no problem at all. So I think this was the issue

Any easy fix for this?
