Yes it works because I’m getting a

[1] 29649 segmentation fault (core dumped) ./ccx\_2.17\_i8  
at runtime (second increment) due to  
Program terminated with signal SIGSEGV, Segmentation fault.  
#0 0x0000000000e3381e in performLightLsMV ()

so I think it works (and I made a mistake while compiling…)
