To me this result looks like a false positive (I'd guess that this `strlen`
call is well-defined and returns 1, but I'm not familiar with the exact rules
for C++ temp objects).
If this is indeed a false positive, then either fix it, or add a comment like
"FIXME: In this corner case the checker produces a false positive".
If the report is a true positive, then perhaps explain why is it a true
positive.
