installs wheels with Python 3.8.How to Reproduce

Details
In pep425flags here when constructing our ABI tag, we check:
sysconfig.get_config_var('SOABI')
, then use thatsysconfig.get_config_var('WITH_PYMALLOC')
, addm
m
On Windows, neither
SOABI
orWITH_PYMALLOC
are defined, so then we unconditionally addm
to our required ABI tags for CPython. But this is incorrect sincem
was removed from the ABI as part of 3.8 per bpo-36707.On macOS and Linux we already have the correct tag since
SOABI
is defined.See also
