Hi Susukita,

$ time ./a.out
real    0m4.324s

$ gprof a.out
Each sample counts as 0.01 seconds.
% cumulative self self total time seconds seconds calls s/call s/call name 9.46 43.22 4.09 rand

This looks like a gprof bug. Specifically I would guess that either the sample period is incorrect or else the clock frequency calculated by the gprof/hertz.c:hertz() function is wrong.
