Solidity compilation can sometimes fail with error about isDevMode()

This issue can happen in the definition of devMode (source file)

The current function signature is function devMode() internal view returns (bool), a view function.
The problem arises by the fact that forge fails to compile the function complaining that this function can not be view, but we didn't see this compilation error in CI and it doesn't seem clear why this function should not be view.

It's not clear if the problem is a compiler version mismatch or something else.
