Current SAST container fails

The current version (within the last 2 days) of the SAST container fails then trying to merge results. The exact error message is:

2019/08/23 21:15:41 Error response from daemon: error processing tar file: docker-tar: relocation error: /lib/x86_64-linux-gnu/libnss_files.so.2: symbol __libc_readline_unlocked, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference : exit status 127

I get this on every SAST scan - it doesn't seem to matter what scanner is run. I also reran a previous job that had worked and it now fails using the latest SAST container with the above error. After the first scanner (whatever that happens to be) completes, the above error message occurs.

This may be related to this: https://github.com/moby/moby/issues/39449

If the SAST container is (essentially) issuing a docker cp, then the above may well be the issue.
