Bug #7622: Can't grab exceptions at (|c_|b_)return event hooks
https://bugs.ruby-lang.org/issues/7622

Author: ko1 (Koichi Sasada)
Status: Open
Priority: Normal
Assignee: ko1 (Koichi Sasada)

Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2012-12-21 trunk 38515) [i386-mswin32_100]


The following code raise uncaught error:

test.rb:14:in `block in <main>': FooError (FooError)
  from test.rb:3:in `m1'
  from test.rb:7:in `m2'
  from test.rb:19:in `block in <main>'
  from test.rb:17:in `times'
  from test.rb:17:in `<main>'

But should be caught at line "rescue FooError => e".

# code:
def m1
  raise
end

def m2
  m1
end

class FooError < Exception; end

TracePoint.trace{|tp|
  p tp
  raise FooError if tp.event == :return && tp.method_id == :m1
}

1.times{
  begin
    m2
  rescue FooError => e
    p e
  end
}

`ensure' is also ignored.
