Problem: Docker implicitly prepends "sh -c " to the RUN commands (no "-e"). Without "-e", the exit code of the shell script is the exit code of the last executed command. So the sample compilation script will only fail if the last sample failed the compilation.
Fix: Explicitly adding "set -e" to the command fixes the issue.
Fixes #1735
