It would be nice to figure out why you have non-zero runs and sum_max zero. It is legally possible when you build your main w/o profiling and exit early, but I would expect this to be bug in Mozilla's FDO build rather than intention. It can easilly happen when you profile library and load it into something that do not use it.
