The error is "C1001: Internal compiler error." in uci.cpp on line 370 of
master. For some reason the compiler can't handle the
std::size(hashfullAges) inside the lambda. Older MSVC versions had no
problem.
Most of the warnings are due to implicit type conversions "conversion
from type A to type B, possible loss of data"
many of which have been present for a while.
