asserts js debug shell with -m on JM tip at Assertion failure: js_ReconstructStackDepth(cx, script, pc) == stackDepth, at ../methodjit/BytecodeAnalyzer.cpp:91
The bytecode analyzer was assuming anything after a JSOP_GOTO would have at least one incoming edge, which isn't true in this case since it's an infinite loop.

forgot to attach the bugno on this cset sorry: http://hg.mozilla.org/users/danderson_mozilla.com/jaegermonkey/rev/b6271e02f257
