pulse audio plugin seg fault on scratch in 64 bit 12.04

[Amos Blanton]

To reproduce:

1. Execute Scratch using current VM and pulse plugin (on Ubuntu 12.04, 64 bit system):
Executing: /usr/lib/squeak/4.4.7-2357/squeakvm -encoding UTF-8 -vm-display-x11 -xshm -plugins /usr/lib/scratch/plugins/:/usr/lib/squeak/4.4.7-2357/ -vm-sound-pulse /usr/share/scratch/Scratch.image
(There is no pulse plugin in /usr/lib/scratch/plugins in my installation package, so it must be using the one in /usr/lib/squeak/4.4.7-2357)

2. Click "Sounds" tab, click play icon next to meow. That results in:

Segmentation fault

10273532 [] in SoundPlayer class>playLoop
10262332 Semaphore>critical:
10262240 SoundPlayer class>playLoop
10273228 [] in SoundPlayer class>startPlayerProcessBufferSize:rate:stereo:
10273320 [] in BlockContext>newProcess
Aborted (core dumped)

Note that the installation of the same package on 32 bit systems does not produce the error (playback and recording both work).

The proposed fix has not been submitted to the Ubuntu package repository as of Ubuntu 13.04. Scratch still will not work on 64 bit systems.

This bug was fixed in the package squeak-vm - 1:4.10.2.2614-1ubuntu2
