Hello Jing,

Here is a small test case that runs into a bad_alloc error:

#include "Halide.h"
#include <stdio.h>
using namespace Halide;
int main(int argc, char **argv) {
    Func e, f, g;
    Var x;
    e(x) =x;
    f(x) = e(x);
    g(x) = f(x); 

    Var xi, xo;
    g.split(x, xo, xi, 16).accelerate({e}, xi, xo);
    f.linebuffer();

    Image<int> out = g.realize(100);//, target);
    return 0;
}

Halide-HLS]$ ./t
