# apk add gcc gmp python3-dev  # along with the regular goodies to get pip3 and python3
# pip3 install pycryptodomex

... have lunch or tea ...

# python3 -m Cryptodome.SelfTest

I'm afraid I do not understand the suggestion. Yes, I've gotten pycryptodomex to build and install [using python3, not python2] But code which tries to use it crashes, and simply running its own self-test as I demonstrate above causes a crash.

If responding looked like a help suggestion, my apologies. The original bug-report seemed sufficient, and though the accompanying data was not indicative that you might've been un/aware of how nor whether it is or is not desirable to formulate any workaround, others might have taken similar routes and thought failure was the accepted option.
