Ah, excess FP precision issue at:
double x, yy, array3[NUMBER], array4[NUMBER];
double max_value = 0.000, min_value = 0.000, add_value, mul_value = 1.00;
...
if (x != max_value)
return 1;
Breakpoint 1, main () at
/home/uros/gcc-svn/trunk/gcc/testsuite/c-c++-common/cilk-plus/AN/builtin_fn_custom.c:62
62 if (x != max_value)

These tests need either checks with tolerances or -ffloat-store.
