PGO-instrumented binary seems not to specify the stdlib directory on PR29041. I can run it with PYTHONPATH set.


Python path configuration:
  PYTHONHOME = 'C:\Py311\'
  PYTHONPATH = (not set)
  program name = 'C:\Py311\PCbuild\amd64\instrumented\python.exe'
  isolated = 0
  environment = 1
  user site = 1
  import site = 1
  is in build tree = 1
  stdlib dir = 'C:\Py311\PCbuild\Lib'
  sys._base_executable = 'C:\\py311\\PCbuild\\amd64\\instrumented\\python.exe'
  sys.base_prefix = 'C:\\py311\\'
  sys.base_exec_prefix = 'C:\\py311\\'
  sys.platlibdir = 'DLLs'
  sys.executable = 'C:\\py311\\PCbuild\\amd64\\instrumented\\python.exe'
  sys.prefix = 'C:\\py311\\'
  sys.exec_prefix = 'C:\\py311\\'
  sys.path = [
    'C:\\py311\\PCbuild\\amd64\\instrumented\\python311.zip',
    'C:\\py311\\PCbuild\\Lib',
    'C:\\py311\\PCbuild\\amd64\\instrumented',
  ]
