[Icecast] IceS segmentation fault

[Greg Jetter]

A quick look at your xml code , reveals several  errors in format  , your  xml needs to be well formed and correct  or the  interpreter  will  puke .  this mite not be your problem but you should fix it first .

Neither a comment outed  line of code  nor a well formed xml  tag.
also take a look at your system log  for the time frame your  launching  the application , it may reveal what’s causing the segmentation fault.

> I've changed nearly every parameter in it to see if I can get round it, but all I am able to achieve is causing a crash sooner than the segfault. I've also got no more logging than this - level 4 is max anyway - so I can only assume the fault is in the encoder. libvorbis and  libogg are both installed. I don't know of any way to use an external encoder or I'd be using that... can anyone help with what might be causing this segfault?
