Workaround MSVC2022 ICE in constexpr functions

It happens around initialization of STL containers in a constexpr
function. In this case, aggregate initialization of std::array with
double braces seems to cause the crash.

For some reason it doesn't seem to happen in 98-based. This workaround
can be reverted after Microsoft fixes the issue:
