Getting strange debugger message: Assertion failed: (cls), function getName: what is this?

Question

Since I upgraded from Xcode 3.2.3 to 3.2.4 and iOS 4.0.1 to iOS 4.1 SDK, when I set a breakpoint in my code and single-step over instructions, at each step, the debugger will sp

I have exactly the same issue. I know it's not the complete answer but here's what I could find.

The relevant function getName looks like this:

/***********************************************************************
* getName
* fixme
* Locking: runtimeLock must be held by the caller
**********************************************************************/
static const char *
getName(struct class_t *cls)
{
    // fixme hack rwlock_assert_writing(&runtimeLock);
    assert(cls);

    if (isRealized(cls)) {
        return cls->data->ro->name;
    } else {
        return ((const struct class_ro_t *)cls->data)->name;
    }
}

So gdb is complaining that the assertion assert(cls) is failing. Which means that getName somehow gets a NULL pointer as an argument.

Which is kinda funny, where could we be asking for the name of a NULL class?

Hope this helps...
