Infinte loop causing game freeze

[Programmdude]

This has only happened since 0.12, it has happened in multiplayer and singleplayer. When playing multiplayer the other clients crashed, while I (the server) just froze. When this happened in singleplayer I jumped into the debugger to see if I could help find the cause.
The renderer thread is still running, so windows doesn't display a "program not responding" dialog, the freeze appears to be related to multithreading, since it is waiting on a mutex. Attempting to do step out while in the debugger simply resumes the game, so WaitForMultipleObjectsEx never completes.
The update thread appears to be stuck in TransportBelt::update.

This is the call stack for the main thread:
ntdll.dll!NtWaitForMultipleObjects()
KernelBase.dll!WaitForMultipleObjectsEx()
Factorio.exe!boost::this_thread::interruptible_wait(void *,struct boost::detail::timeout)

The log file doesn't have much of use, but these are the platform details it gets. I am also running windows 8.1 x64, with the x64 version of the game.

EDIT: I saved a minidump, this forum doesn't allow uploading .dmp files, so I have uploaded it to dropbox.

Stepping through the debugger, the line number of TransportBelt::Update goes from 192 to 195, so whatever is causing the looping is in that region.

EDIT 2: I think it's the same issue as this post: https://forums.factorio.com/forum/vie ... =7&t=13616

Can you post the save file? Does it happen every time on the save?

Edit: I fixed the issue in the linked report. If you have a save I can make sure your issue was the same problem.
