Bug #1995: for-in+binding+local_variables = [BUG] Segmentation fault in 1.9.1p243

Author: Michael Zimmerman
Status: Open, Priority: Normal
ruby -v: ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32]

While playing around with for-in I've found the following bit of code causes a segfault for me:

def kaboom!
  bnd = yield
  p bnd.eval("local_variables")
end

for x in enum_for(:kaboom!)
  binding
end
