[ruby-core:97164] [Ruby master Bug#16633] TracePoint :line event issue

Issue #16633 has been updated by mame (Yusuke Endoh).

Status changed from Open to Rejected

In fact, Line 7 is not reachable.  The return statement in the block jumps to the callsite of foo.

```
def bar
  yield 1
  puts "unreachable"
end

def foo
  bar do |a|
    return a # skips the rest of bar, and immediately returns to the callsite of foo
  end
  puts "unreachable too"
end

foo # the callsite of foo
```
