I think you're misreading the bug report. The warning I see is:
<stdin>:11:40: warning: Value stored to 'bytes' is never read
unsigned bg = *((unsigned*)bytes); bytes += sizeof(unsigned);
^ ~~~~~~~~~~~~~~~~
1 diagnostic generated.
The warning is not about the assignment to bg, its about the "+=" performed to
"bytes". Both the HTML output and console output indicate that the bug has to
do with the expression:
bytes += sizeof(unsigned);
What happens is that the value of bytes is incremented (which is essentially a
load, addition, store), but then that new value stored to bytes is never read.
So this isn't a false positive. There is a dead store here (and a dead
operation).
