Summary:                    Unable to use iLBC codec under virtual machine (nor
Xen, nor VMWare)
Description: 
I'm running Asterisk (as test machines) under various virtual
environnements and am having the same problem under every virtual
environnement I tried.
I had this problem with Asterisk 1.4 before but did not bother mentionning
because I did not want to use the iLBC codec at that time. I think this
issue started when the iLBC source code went out-of-tree.

I'm running a Ubuntu 32-bit guest in a 64-bit server, this one is running
under VMWare Server on Linux.

If I try to run Asterisk with the iLBC codec enabled (with the contrib
script downloading/extracting the source from the online RFC) it segfaults.
I'm currently testing it with asterisk-trunk.

I can successfully start asterisk if I add a noload directive in the
modules.conf configuration file, but I'm missing the ilbc codec in the
supported translations report.

In "additionnal informations", I have the gdb stacktrace (bt) of my core
dump file.

The backtrace seems to originate from VPB drivers (linvpb.so.0 in the
window() function), but I don't any VPB card.
