@zooba: What do you think about this PR? Upgrading MSVC did resolve it, but IIUC the minimum required version of MSVC is 14.0, which would certainly require this change. |

There was a problem hiding this comment.
The choice is either to make a trivial change to keep building, or to go through and declare (and detect and warn) that specific compilers are no longer permitted.
I suspect you'll prefer to just take this trivial change 😉

Looking at this, there shouldn't be a need for the length in here? And while I believe it's okay, it could be affected by this change.

Empty array initializers (
{}) are not strictly standards compliant, and at least MSVC 1935 doesn't support them. This fixes those initializers to be{0}.
