DISTRIB_DESCRIPTION="Ubuntu 10.04.4 LTS"

I'm using a ChucK build with my own modifications (-m32 and some that
are Jack-related).

test case:

fun void foo(string s)
{
	//<<< s >>>;
}

while (true) {
	//<<< 1 >>>;
	"bar" => foo;
	//<<< 2 >>>;
}

result:

rhaberkorn at nb005-lx001:~$ chuck --srate:44100 bug.ck
chuck: chuck_oo.cpp:125: void Chuck_VM_Object::release(): Assertion
`m_ref_count > 0' failed.
Aborted

uncommenting the debug prints:
