[reSIProcate] segfault in SdpContents::Empty when linking statically

[Byron Campen]

	I don't think anyone has the foggiest of what's going on here. I  
have worked with the static libs on linux a great deal with no  
problems like this, but I'm still on gcc 4.0.2. How are you linking  
against librutil when this problem crops up?

Best regards,
Byron Campen
