Bug #5527: set_trace_func binding incorrect
https://bugs.ruby-lang.org/issues/5527#change-62774
* Author: Thomas Sawyer
* Status: Feedback
* Priority: Normal
* Assignee: Koichi Sasada
* Target version: next minor
* ruby -v: ruby 1.9.3dev (2011-09-23 revision 33323) [x86_64-linux]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
set_trace_func seems to be broken. I traced the issue to the binding
(`b` below).
```
$ 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.
