[issue26207] test_distutils fails on "AMD64 Windows7 SP1 3.x" buildbot

Jeremy Kloth added the comment: I'm upgrading the VS installation on my buildbot currently so this should be a non-issue going forward. However, I think it would be good to add/change the bug title to include something about the /LTCG error so as to enable better searching when developers do

Jeremy Kloth added the comment: My buildbot updated to VS2015.1 successfully. test_distutils is passing again. As to the bug title, it should mention the incorrect DLL version error, not the /LTCG *warning*. That's what I get for just doing a quick scan of the comments. -- _

Steve Dower added the comment: This has been confirmed as a bug in VS 2015 RTM that was fixed in Update 1. It only affects debug builds, which are not common and I expect most people using them to be keeping VS up to date. I'd rather not add extra logic to distutils just to detect this case. I

Zachary Ware added the comment: Steve, I'm assuming you meant "x86_amd64" rather than "x86_arm" on that last filename? Note that this issue is restricted to Debug builds (as suggested by the issue being with mspdb140.dll), the Non-Debug buildbot is not failing. -- ___
