My guess is that your CPU lacks sse2, which in turn doesn't support
multi-byte nops, which in turn does not support the endbr opcode / CET.
I built i386 packages without endbr and uploaded everything to
https://people.debian.org/~bigeasy/openssl-3-noendbr/
Could you please give a try report if this is correct?
Sebastian
Yes, with libssl3_3.0.3-4.noendbr_i386.deb this is fixed.
Thanks
