LibC: Don't format strings when asserting with an unstable heap

Browse source 
If we hit an assertion while the heap isn't in a stable state, we can't
rely on dynamic memory allocation because the malloc mutex is already
held and the heap is most likely corrupted. Instead, we need to bail
out fast before we make the situation even worse.
