Comment(by cypherpunks):

 Replying to [comment:45 marshray]:
 > * The address 4c0748 is in the tor.exe process and is the address of the
 next instruction for Tor.exe to run. This code has been paged out. When
 the OS goes to execute the instruction it causes a page fault, which is
 normal. But when the OS tries to load it from the pagefile the kernel
 encounters a corrupted PTE (page table entry). This creates a double-fault
 situation which results in a bluescreen.

 The address 4c0748 belongs to first instruction of nt_service_set_state().
 It called (no mater if tor ran as service or not) only once during initial
 of start-up from tor_main(). How page with it has been paged out? Is it
 about OS caching to page file?
