        <pre>This behavior is correct, and required by the standard. See [expr.const]/14:

"An expression or conversion is manifestly constant-evaluated if it is [...]

the initializer of a variable that [...] has constant initialization"

'globalVariable' has constant initialization, so is_constant_evaluated()

returns true during its initialization.

MSVC has a very long-standing bug where it fails to properly implement constant

initialization for global variables; that's probably why you're seeing a

behavior difference between the two compilers here.</pre>
