Yeah my fault. I mixed up CL and Link Version Numbers:
Link Version is 14.12.25830.2 and
CL Version 19.12.25830.2 but
Compiler Tool Set Version is 14.12

You have to love their Versioning Scheme ;)

BTW: It turned out that the VS SSA-Optimizer is at fault here! After
disabling it with '/d2SSAOptimizer-' blake2b.c compiles fine.

Seems like a Bug with this Tool Set Version.

I created a BR:

Should I create a BR at the VS Forum too?

Have a nice Day everyone

And I'm not building OpenSSL in this case (it's a diffferent project that happens to include Argon2), so it's entirely possible I'm using different compiler options. But there's another data point, anyway.
