Another demonstration of the bug
Unpack and run "make" to build and run it. Requires routine "usleep" from
<unistid.h>. When compiled correctly, it should run without comment.
Otherwise, as with gcc 5.2.0, it will report errors. E.g., here is a sample
session:
$ make
g++ -O0 -std=c++11 -fcilkplus harness.cpp -c
g++ -O0 -std=c++11 -fcilkplus test.cpp -c
g++ -O0 -std=c++11 -fcilkplus harness.o test.o
./a.out
ERROR: f.val=3, should be 2
ERROR: f.val=6, should be 3
make: *** [all] Aborted
