I was trying to update to a revision that contains a file ~86MB. The revision was created on a Windows 7 64-bit system. I am trying to restore on a Windows XP 32-bit system, and update fails on that file.
I attempted to save the file at that revision from the TortoiseHG workbench, and got the backtrace shown below.
