Hard crash during assertion failure (Win 7/64)

[historic_bruno]

OS: Win 7 64-bit
Build: VS 2010 Pro - release build

While testing #1812 I encountered an assertion failure, but there was a hard crash before the error dialog was displayed:

Simulation2.cpp(329): Assertion failed: "0 && (L"Serialization test failure")"
First-chance exception at 0x522d7c77 in pyrogenesis.exe: 0xC00000FD: Stack overflow.

Unhandled exception at 0x52322203 in pyrogenesis.exe: 0xC0000005: Access violation writing location 0x02e00de8.

Here's the call stack for all threads at the time of the crash: ​http://pastebin.com/Kc3aLKtP

I don't know what could cause this, but we currently have a bug where a thread is running constantly and frequently accessing timer_Time(), if that's relevant. This is not consistently reproducible but these steps work for me with r13045:

• Start the game in Atlas with serialization test mode: -editor -serializationtest
• Load "Acropolis 01" map
• Start simulation test
• Select a soldier and task him to build a house, triggering the serialization test failure, and sometimes the crash
