Steve Dower added the comment: Just made another "release" build from the latest source (with OpenSSL 1.0.2h) and can no longer repro this issue, so I'm closing it. If anyone wants to try with the same build, it will be up at https://ptvs.blob.core.windows.net/temp/python-2.7.12.amd64.msi for

Steve Dower added the comment: A build issue like that is fairly likely - I don't touch 2.7 apart from releases and so all I did was restart my build VM, pull and hit rebuild. There may be another clean step required when the OpenSSL version changes. We're getting another update before the

Steve Dower added the comment: It seems to work fine on my build machine (Win Server 2012) but not my laptop (Win 10 Home). I suspect there's a different certificate being loaded that's causing the crash, but until I get a chance to debug properly I can't be sure. Hopefully I'll get a chance

Tim Golden added the comment: I did wonder about that. It's good that we can reproduce the issue without pip, but it's probably going to be messy to debug! I've got VS 2008 on this machine but no time at the moment to build & debug. Don't know if Zach or Steve might be able to jump in. If not,
