I’m building an image on Ubuntu 16.04 (4.10.0-33-generic #37~16.04.1-Ubuntu, stretch) using C++. Then using docker (version 17.12.0-cd, build c97c6d6) to build an image. It runs fine on this machine. It also runs fine in Windows 10 Pro with docker version 17.09-1-ce, build 19e2cf6).
The lscpu
for the build machine is:

Then I loaded it onto Debian 7.11 (3.16.0-0.bpo.4-amd64 #1 SMP Debian, wheezy) using the same version of docker. When I run my program, it immediately stops after printing the message “Illegal instruction”.

Other programs in this same image run.
This program contains my own code plus RocksDB, gRPC, Boost and another proprietary library.
I’m not sure where to look. Is there a compiler option is should use to generate instructions for older CPUs?
Anything else I should look at?
