Emacs-24 branch revno 111270 hangs after package-list-packages (w7-x64) No response with C-g, C-Break or close application button Win Task Manager shows emacs process increasing its size continuously. Emacs-24 branch revno 111269 runs perfectly (w7-x64) Emacs-trunk branch revno 111817 runs perfectly (w7-x64) I build emacs regularly with no issues, so I do not assume building process mistakes. (thanks in part to Dani Moncayo) By the way, the fastest nt-emacs version ever.
