Bug report
Summary:
With stdlib re included in Tools/scripts/freeze_modules.py as in the following snippet
('stdlib - startup, with site', [
'_collections_abc',
'_sitebuiltins',
'genericpath',
'ntpath',
'posixpath',
# We must explicitly mark os.path as a frozen module
# even though it will never be imported.
f'{OS_PATH} : os.path',
'os',
'site',
'stat',
'<re.*>',
]),
the following build error occurs
./python.exe -E -S -m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
echo "generate-posix-vars failed" ; \
rm -f ./pybuilddir.txt ; \
exit 1 ; \
fi

Python.exe manages to build even with the error and I was able to reproduce the re.error multiple times when trying to run the following snippet:
blank_re = re.compile(br'^[ \t\f]*(?:[#\r\n]|$)', re.ASCII)
This error only occurs when the re module is frozen and does not occur when re is imported normally from Lib PATH.
