    Details

    • Type: Bug
    • Status: Closed
    • Priority: P1: Critical
    • Resolution: Cannot Reproduce
    • Affects Version/s: 5.2.1
    • Fix Version/s: None
    • Labels:
      None
    • Environment:
      Failing: ARM (armv7l), with gcc 4.6.4
      Working: x86_64, with gcc 4.8.1

      Description

      On running the attached example, I get this log:

      outer.foo undefined
      inner.bar inner.bar
      parent value outer.foo
      

      But, if I uncomment the commented line, then outer.foo gets defined.

      This happens running on ARM (armv7l). If I try the same version on desktop, with x86_64, it works as expected (both with the line commented and uncommented).

      But, if I add the following patch that got landed after 5.2.1 release:

          [Regression] Fix lazy binding evaluation
      

      Then the result is reversed:

      • With the commented line, it works.
      • Uncommenting the line, it fails.

      Adding also this patch still doesn't fix the issue:
