today I tried to compile Redis with clang, and a test was failing
without apparent reasons.
I investigated a bit further, and isolated the bug in the following
code fragment:


I verified the bug only in Apple's clang, I'm not 100% sure this is
the right place where to submit such a bug report. If this is the
wrong place, I'm sorry, please point me in the right direction.
