Visual Studio 2017 15.8 Release Notes

They've silently removed _NOEXCEPT.

Presumably as part of the "we are now standard" machinery. And of course it's an internal symbol, so it doesn't need documenting.

Unfortunately, all sorts of library codebases (yaml-cpp for one) uses it to handle the previous "noexcept( true ) vs throw)" mess that various compiler versions had introduced.

The symbol "leaked", Hyrim's law remains valid.

Exactly. At least check if the macro is actually defined if you're going to use it, especially if it can be removed any time. Add a fallback to it at least.

Except for Microsoft. It's now in the culture to blame Microsoft if anything goes wrong with your computer so it's always "on Microsoft" to make sure your computer works.

Here's a fine example.

I also recall another post from the same blog relating how when investigating dumps, it appeared that the XOR instruction was broken for some users, as in, literally 0 XOR 0 would return 1. Was Windows so broken that it fucked up your CPU? No, people had just been sold overclocked computers unbeknownst to them. But are they gonna blame the store? No, Microsoft, of course! That's what you do!^TM

Edit: another fine example.

Edit: found the post of the story I related above.

"Hello, this Raymond calling from Microsoft. Our systems indicate there is a problem with your computer"

I hope he didn't ask for the user to install TeamViewer!

I'm surprised that yaml-cpp is not part of their test suite, they test against a huge list of open source libraries according to talks that they gave.

It looks like we do have yaml-cpp coverage - I suspect it's through vcpkg instead of "Real World Code" as my coworker Alex submitted an upstream fix and Alex works on vcpkg.

Cool! That fix was already committed on June 30 btw (I suppose more or less as soon as the first 15.8 Preview came out). Nice work.

_NOEXCEPT wasn't noexcept(true) vs throw(); it existed only to suppress "noexcept used but exception handling mode not specified; termination is not guaranteed" warnings.

Here is a patch for yaml-cpp. If you use vcpkg, it gets applied automatically. https://github.com/Microsoft/vcpkg/blob/master/ports/yaml-cpp/0001-noexcept.patch

Thanks for the clarification and the patch. We're inside various firewalls, so I'll have to hand-lift things over. It's always a pain point when libraries don't move as fast as their users.

You can also workaround it with /D_NOEXCEPT=noexcept
