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 '

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
