autoBisect shows this is probably related to bug 529837:
The first bad revision is:
changeset: 35214:a71067721eb0
user: Brendan Eich
date: Tue Nov 24 15:15:37 2009 -0800
summary: Undo hackaround for bug 529837.
I am not sure why autoBisect points to a different checkin, and the testcase in comment #0 affects both 32-bit and 64-bit in Snow Leopard 10.6, in contrary to comment #1.

$ ./js-dbg-32-tm-darwin
js> ({x:function(){}}).watch('x',function(){});
Assertion failure: !sprop->isMethod(), at ../jsscope.cpp:1472
Bus error
Now asserts in a slightly different assert message on TM tip without -j in a debug js build.

After the assertion morphed, this assertion is now occurring somewhat more often in jsfunfuzz.
