[gentoo-user] esound/esd segfaults

[William Kenworthy]

Hi, I have had a problem for many months where esd segfaults on two
systems.  Sound and alsa (alsa-lib is 1.09) work fine.  In the past
there were esd-alsa API problems, but they have been solved - right?

strace shows nothing obvious up until the segfault.  Where can I look
next?

The last part of a strace shows:
