Today I updated one of my systems here to fedora core 4,
got and built all the alsa drivers/tools/libs, csound, libsndfile,
portaudio, etc.

Now Csound5 crashes with portaudio, but runs OK with the
alsa module. Alsa 1.0.10, portaudio tarball from today.
Any suggestions why portaudio is crashing?

The csound tidy up: segmentation fault comes just after
the PortAudio v19 Devel message.

No, there is no old version of portaudio, since I have installed
everything from scratch and as far as I know Fedora Core 4 does
not ship portaudio, but I'll check anyway.

and what's more: the portaudio tests also cause segmentation fault;
so I guess it's portaudio then. I'll let them know.

Found the solution. The /dev/dsp symlink had not been created,
so portaudio did not like that (althought Istvan's alsa module did not
complain). I had not re-booted after installing alsa (with alsaconf);
after the re-boot all's well.

Device 0 (-odac) for portaudio is /dev/dsp (OSS), so that's why.
