[New-bugs-announce] [issue47037] Build problems on Windows

[Terry J. Reedy]

New submission from Terry J. Reedy <tjreedy at udel.edu>:

3.11 apparently builds without error, and 'python' and 'python -m idlelib' appears to start normally, but there is a new problem.
  python -m test
raises OS box with 'Debug Assertion Failed!', program python_d.exe,
File minkernal\crts\ucrt\src\time\wcsftime.exe
Line 1184, expression false.
Dismiss box and a few tests run until box repeats and Command Prompt eventually locks.
...test test_idle finished OK once after dismissing box.  On retry, test ran OK but CP locked instead of showing new prompt.

3.10 and 3.9 (but not 3.11): compiling show a newish warning.
  pythonw.vcxproj -> f:\dev\310\PCbuild\amd64\pythonw_d.exe
  pythonw.vcxproj -> f:\dev\310\PCbuild\amd64\pythonw_d.pdb (Full PDB)
f:\dev\310\PCbuild\pythoncore.vcxproj(554,5): warning : A copy of vcruntime140.dll is also required

Does not 3.11 also require this? (wherever it is supposed to be?).  Aside from the warning, 3.10 appear to be working normally.  There is no error box when starting tests and 50 have run so far without a box.
