Squeezeslave crash with audio stream

[Rukapul]

I'm having a problem with Squeezeslave, which crashes when playing Internetradio.

In particular the problem repeatably occurs with the Dutch "3FM" audio stream. Squeezebox Server lists the following url for the steam: opml.radiotime.com/Tune.ashx?id=s124127&formats=aac,ogg,mp3&partnerId =16&serial=977e69e221e1df668964da983ff434f5

Squeezeslave gives the following error:
squeezeslave: src/slimaudio/slimaudio_buffer.c:288: slimaudio_buffer_read: Assertion `len > 0' failed.

Squeezeslave versions tested: 1.1-253 and SVN (trunk)
Squeezebox server version: Version: 7.6.1 - r33110
Squeezeslave and squeezebox server run on the same Debian Squeeze () machine.

Any chance for a fix to this problem?

Those playingSong undefined errors are not related and were fixed in a later version of 7.6.

I've tested this url

with this server version running on ubuntu

Version: 7.6.2 - r33532 @ Wed Sep 28 02:03:14 PDT 2011

with squeezeslave

squeezeslave 1.1-281 Aug 31 2011 14:32:02
compile flags: linux portaudio:1608 debug signals interactive daemon

and was unable to reproduce the crash.

During my testing the AAC stream was being used and transcoded to flac using faad on the server.

Thanks for the reply.

I should have added to my initial post that the crash only occurs after multiple hours. Furthermore, I learned that long before that the stream will have lost working (typically after 30-60 minutes) and needs a restart.

So, although something causes the assert to go off there seem to be intrinsic problems with the stream itself. As far as I understand convert.conf (unmodified debian package default) conversion is same as in your case.

Since I have found an alternative source for the same internetradiostream which does not seem to crash I'll leave this issue for what it is. At the end of the day only the WAF matters
