            Bug ID: 48329
           Summary: lld fails linking an msvc object file with "permission
                    denied"
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: COFF
          Assignee: unassignedbugs at nondot.org
          Reporter: dpldobrev at protonmail.com
                CC: llvm-bugs at lists.llvm.org

I'm trying to link msvc with the latest lld,
f502b14d40e751fe00afc493ef0d08f196524886 from llvm-project. I get this:

lld-link: error: permission denied

I debugged it and saw that this occurs while writing the import library which
is now obligatory with msvc. A temporary file's created for the .lib, with a
temporary name. When lld attemtps to rename the .lib to its real name, this
fails. I've also noticed the .lib has 0 bytes of content just before renaming
is attempted.
This is my code: https://pastebin.com/WT0C5JPu . It works with revision
0c8f9b8099fd0500cd885bc699924e20371014ff.
