Hello Juha,
There are around 180~200 of these defects found when using a static
analysis tool like llvm's scan-build. I have patched some of them (which
were bugs), but most of these dead assignments are removed by the
compiler anyway on -O2 optimisation level. GCC it's just playing a
catch-a-mouse game with better static analysis tools. I can provide a
list of all these defects, if someone it the community wants to take the
time to fix them.
Cheers,
Marius
