  Umm, you don't need that much memory to open a file, thanks to the wonders of file-backed virtual memory.  But what you probably do need is a 1.5GB empty hole in your process address space (unless vim is intelligent enough to only mmap() part of the file at a time), and finding a hole that size is almost certainly impossible on 32-bit targets without enabling the boot.ini '/3GB' switch.

  However I don't know anything about the internals of vim, so can't be sure that's the cause.  And it's certainly a bug that it doesn't fail gracefully.

Can't think of a witty .sigline today....
