Should this be buildable with VC++17 ?

Sorry, but I can't try a version higher than 17.6.5.

In case anybody else gets a chance, I've just had a reply back from Microsoft to say that 17.1 gives the errors I reported (C2182) and 17.2 gives the errors that 2kaud reported (C7683) but they're saying it's definitely been fixed since 17.11.3

Unfortunately (AFAIK) it isn't possible to install 17.11.3 using my current compiler, VS2019 - and I don't have enough disk space at the moment to install/upgrade to VS2022

I've now installed VS2022 onto a Windows 10 machine so that I can use the latest version (I normally use Windows 7 and 17.6.5 is the last version that will install with Windows 7).

I can confirm that the code compiles OK with 17.11.5.

I don't have enough disk space at the moment to install/upgrade to VS2022

If you're using Windows 10/11 then why not remove VS2019 and then install VS2022? VS2019 projects will convert to VS2022 OK. Also, if you're short of disk space have you removed any unwanted options from VS2019 using VS installer?

This might be my lucky day... I just did a disk cleanup and I'd nearly 12GB just in VS debugging reports! So after the cleanup I've now around 23GB of space remaining. If I get a chance later I might install VS2022 onto a memory stick (just to check how much space it'd take up)

One more thing 2kaud if you don't mind... if you've still got VS2022 installed on Win10, would you mind checking if my code will compile with C++17? The guy who wrote it seems to think it should - whereas the guy from Microsoft suggested it was C++20.

You might also want to check the crashdump folder! (<user>\AppData\local\crashdumps)

VS2022 17.11.5 using Toolset 2022 (V143)
C++20 - OK
C++17 - OK

VS2022 17.11.5 using Toolset 2019 (V142)
C++20 - NO
