Reproducable Panic on CURRENT and 6.0-RELEASE

Here is the offending program/code.  The interesting program is 
avidemux_2.1_branch_anish/avidemux/avidemux2.
(It is compiled for CURRENT, and I left all the object code stuff in 
so it's a bit large 21MB)
http://am-productions.biz/docs/avidemux_2.1_branch_anish.tgz

First you'll need to compile spidermonkey to be threadsafe so add the 
following to your lang/spidermonkey/Makefile before installing it:
LIB_DEPENDS=    nspr4.1:${PORTSDIR}/devel/nspr
MAKE_ARGS+=     JS_THREADSAFE=YES LDFLAGS="-L${LOCALBASE}/lib 
-lpthread -lm"
CFLAGS+=        -I${LOCALBASE}/include/nspr

Once a threadsafe spidermonkey is installed to kill the machine you'll 
need to:
cd avidemux_2.1_branch_anish/avidemux
./avidemux2 --run new-features-test.js

On CURRENT:

From my previous email to questions with the info on 6.0-RELEASE:
I'm getting the following panic, which I can reproduce easily.  Let me 
know what other information I should provide.  The backtrace seems 
really short for some reason.  I get the panic when running a 
multi-threaded application I'm developing/modifying.

I have firewire console access to the CURRENT system, and serial 
console access for the 6.0-RELEASE.

Thanks,
