I can reproduce the problem in win32 (perl 5.12.3), but not on linux (perl5.12.3, 5.12.4 or 5.14.2). So since it's the same code on all 3 versions, I would think it's a bug somewhere in Scalar::Util::weaken or in the core, but only on windows. Which is a bit annoying since I don't develop on windows, I only use it to test modules before a release.
I am not sure where to go from there honestly. Any idea?
