            Bug ID: 45750
           Summary: Windows snapshot build v11 runs high on memory,
                    sometimes out of memory
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: mtlmeijer at gmail.com

First, please note this was only a problem seen with the Windows snapshot build
v11 from:

https://llvm.org/builds/
LLVM-11.0.0-2663a25f-win64.exe


This is not a problem with v10 nor v9 from:

https://releases.llvm.org/download.html
LLVM-10.0.0-win64.exe
LLVM-9.0.0-win64.exe


I see that v10 (20 Mar 2020) is newer than v11 (3 February 2020), so the v11
page or build is outdated?
https://releases.llvm.org/


The problem I had, when building with clang from Visual Studio 2019, is it used
a lot of memory (20gb+), sometimes ending with the LLVM out of memory error.

With v10 and v9, it runs below 1gb.


I can provide more details. But first worth considering the Windows snapshot
page is replaced by the releases page?
