Bug Description

According to the upstream GitHub rocksdb uses "-march=native" by default[0] so for portable binaries one has to use "PORTABLE=1 make …".

For the librocksdb4.1 package in Ubuntu 16.04 this seems to not have been done. Consequently trying to use this package on an older Xeon E5649 (even though that claims SSE4.2) results in an immediate crash with "invalid opcode" in dmesg.

When I compile from source on this same machine using

"apt-get source librocksdb-dev" and "dpkg-buildpackage -us -uc" results in a working build.

The linked Debian bug has been fixed in rocksdb 4.5.1-1 and therefore also in Ubuntu 20.04 (bionic). Ubuntu 16.04 is EOL now.
