I was running into where if a string in the argument list contains a printf escape sequence, we would segfault. In particular, I was using opal_output to print the environment and had something like: LESSOPEN=|/usr/bin/lesspipe.sh %s in my environment. So I called opal_output(0, "%s", environ[i]) and got a segfault because the fprintf tried to expand the %s in the environment variable This commit was SVN r12094.
