segfault with IceS2 (looks like use-after-free() in libshout)
I was running two ices-2 in parallel, and one of the two crashed. The other, as well as Icecast are still running fine.
This is on OpenBSD 3.8 (i386), which contains some interesting changes to malloc(). Misbehaving software gets a SIGSEGV here, while on other systems, the same bug might only occasionally cause a seemingly random crash. It is explained at http://marc.theaimsgroup.com/?l=openbsd-misc&m=112475373731469&w=2
Versions are ices-2.0.1, libshout-2.1 and icecast-2.3.0.
The tail of the ices.log:

I'll be happy to help with more information, if necessary, also on Freenode/#icecast (_mx). I will also restart the whole thing with libshout having debug symbols; maybe it happens again.
