[pulseaudio-discuss] alignment trap and pulseaudio being kiled

[Baek Chang]

Hi,

Trying to debug pulseaudio 0.9.22 and I am seeing some alignment trap
warnings from kernel

[ 1564.095562] Alignment trap: alsa-sink (5580) PC=0x2ab2ca3c
Instr=0xe1ca00d0 Address=0x2af9302a FSR 0x011

I tried connecting to gdb and reproducing the issue, the problem is that
pulseaudio doesn't crash, but eventually terminates.
Any ideas on how to debug this?

Thanks
Baek
