espeak crash, most likely due to portaudio

I'm trying to work with espeak. I have a beagleboard, running angstrom
CLI only.

I first installed it and portaudio (v19) from source. It works fine
the first time I run it, but crashes at the second test. A long error
message comes out, complaining about audio related stuffs, with lots
of hex dump. Unfortunately I can't log that message... At the end it
says: "Fixing recursive fault but reboot is needed!" And then
everything is frozen.

I also tried with espeak provided by opkg, but it gives exactly the
same.

And test programs in portaudio patest_longsine yield the same error.

Is anybody using portaudio or espeak on beagleboard / angstrom?
