Bug #7635: debug_inspector API segfaults when opened from inside an eval 
frame

(({rb_debug_inspector_open})) segfaults when it is called from inside an 
eval frame.

Using this C extension:

  #include "ruby/ruby.h"

  static VALUE
  cb()
  {
      return Qnil;
  }

  static VALUE
  debug_inspector()
  {
      return rb_debug_inspector_open(cb, NULL);
  }

  void
  Init_debug_inspector()
  {
      rb_define_global_function("debug_inspector", debug_inspector, 0);
  }

Calling (({debug_inspector})) from the top level and from within methods 
works fine, calling inside eval from the top level works fine, but 
calling inside eval from within a method segfaults.

Here is a test program that segfaults:

  require "./debug_inspector" # the c extension above

  def x
    eval "debug_inspector"
  end

  x

=end
