Snd Write Waveform.vi not run on Suse platform

[Saphir]

in lvsound.so, VI 'Snd Write Waveform.vi'

Configuration : LabVIEW 7.0

OS : Suse 9.3

Alsa v 1.0.8 and 1.0.9

This function makes LabVIEW to exit!

It works perfectly with RedHad 9.0, XP and MacOSX

The behaviour is different between source and executable :

- source : no trouble before executing this VI

- exe : the main application loads and runs as expected.

As soon as it launches a subpanel calling this subVI it makes LabVIEW to quit.

Hi,

I have reproduced this problem and have been trying to figure it out for

a few hours now. It seems to happen on LabVIEW 7.0 only for SuSE 9.2

and 9.3 (both kernel 2.6 based), when running the SO Config.vi.

I have something for you to try. Please replace the file lvsound.so in

the LabVIEW resource directory (usually /usr/local/lv70/resource) with

the attached version.

On my system, this avoids the crash, which appeared to be caused by a

problem in the system pthread library trying to unwind the stack during

pthread exit. (The sound library uses threads to asynchronously

read/write data to the sound device.)
