Package: libspa-0.2-modules
Version: 1.0.1-1
Severity: important
Dear Maintainer,
Sometimes ...mostly be load growth a lot..., pipe-wire daemon or
pipewire-pulse daemon crashes with below message [1].
This happens misalign of loading to YMM register [2][3].
This crash seems to happen at "vlddqu -0x20(%rcx),%ymm2" [2],
this need align at 256bit (but, Older Ryzen may be need only align of
128bit).
But, RCX register didn't align of 256bits [3].
Value is 0x5650f98e99c4 .
So, software related libspa-audioconvert crashes sometime and randomly.
I think.
Best regards,
Ohta.
