set_trace_func binding incorrect
ruby 1.9.3dev (2011-09-23 revision 33323) [x86_64-linux]
set_trace_func seems to be broken. I traced the issue to the binding
$ cat t.rb fn = lambda do |e, f, l, m, b, k| p Kernel.eval('self', b) end set_trace_func(fn) " a ".strip $ rbenv shell 1.8.7-p352 $ ruby t.rb main " a " " a " $ rbenv shell 1.9.3-rc1 $ ruby t.rb main main main main
It would seem the binding has somehow become the binding-of-caller, rather than receiver.
