Don't you think the warning will be very noisy? I assume most programs have a lot of cold error handling functions etc. that are never executed in a normal execution. Like how does it look like for a gcc build for example? I suspect it would need some heuristics to cut it down at least, like if the function ends with exit (perhaps propagated through the call tree) it's not flagged. Or if there is warning for a function don't warn about callees that are not called from somewhere else. -Andi
