JS_HandleTrap is also throwing an ASSERT and aborting at times.  Its
definately related to clearing a breakpoint that I'm currently sitting on
and then contining execution.

This line asserts ->     JS_ASSERT(0);   /* XXX can't happen */

Heres the body of the function causing the assert.
JS_HandleTrap(JSContext *cx, JSScript *script, jsbytecode *pc, jsval *rval)
{
    JSTrap *trap;
    JSTrapStatus status;
    jsint op;

    trap = FindTrap(cx->runtime, script, pc);
    if (!trap) {
        JS_ASSERT(0);   /* XXX can't happen */
