Internet / Re: Problems with OpenSSL library after update.

It appears it should be possible to configure OPENSSL at runtime to avoid attempting to use the problematic code via the OPENSSL_ia32cap environment variable.
See
https://docs.openssl.org/1.1.1/man3/OPENSSL_ia32cap/#description
and
https://stackoverflow.com/questions/40091888/how-to-disable-avx-instructions-in-openssl
For the curious, the relevant code is at
crypto\cryptlib.c:694
if ((env = getenv("OPENSSL_ia32cap"))) {
in the netlabs openssl sources.
