Find some error with exception

ruby-talk
1

run following script

···

---------------------------------------------
def foo(i)
    foo(i+1)
end
def main1
    begin
        foo(1)
    rescue
        puts $!.backtrace.join("\n")
    end
end

def main2
    begin
        foo(1)
    rescue
        puts $!.backtrace.join("\n")
    end
end

main1
main2
----------------------------------------------
this will has to "stack too deep" error at DIFFERENT line of the script
but the result will be

mm.rb:2:in `foo'
mm.rb:2:in `foo'
mm.rb:8:in `main1'
mm.rb:22
mm.rb:2:in `foo'
mm.rb:2:in `foo'
mm.rb:8:in `main1'
mm.rb:22

both show the 1st error position
this error should be correct

What are you trying to accomplish? Infinite recursion is generally not
a really good idea unless you want to cripple your machine
temporarily.

What are you trying to accomplish?

Read *carefully* his message.

main1

   ^^^^^

main2

   ^^^^^

mm.rb:8:in `main1'

               ^^^^^

mm.rb:8:in `main1'

               ^^^^^

In NODE_RESCUE, ruby_errinfo is reset to Qnil (well to e_info) but the
backtrace is not reset, this is why ruby not rebuild it.
