Okay, I'll try and see if I can reproduce the issue on my machine at some point later in the week. It might be helpful to try debugging the tool or adding some instrumentation that dumps the current memory usage on Windows periodically, to try to understand why the tool's usage is higher than we might expect. It could be simply the way the file is opened and maintained by Windows, but I don't know enough about file systems or the LLVM underlying implementation to be able to comment really. @hvdijk, do you have any ideas?
