3.22 regression: Crash with 32bit clang + mingw + TIMESTAMP

Downstream issue: https://github.com/msys2/MINGW-packages/issues/10152

Starting with 3.22 (3.21.4 works) the following crashes:

CMakeLists.txt:

string(TIMESTAMP DEFAULT_BUILD "%Y%m%d")

$ cmake -GNinja .
-- Building for: Ninja
CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.
