Segmentation fault while running thrust::lower bound in a HIP kernel

Having a HIP Kernel with thrust::lower_bound causes a crash. The same call if used in the host code and not a HIP kernel works ok!
A simple test that causes a crash is:
#include <thrust/binary_search.h>
#include <thrust/execution_policy.h>
#include <thrust/functional.h>
#include "hip/hip_runtime.h"
__global__ void kern(
int N,
float* inp,
float val)
{
auto low_bound = thrust::lower_bound(thrust::device, inp, inp + N, val);
}
int main(void)
{
float * input_device;
hipMalloc(&input_device, sizeof(float)*6);
float value = 5;
hipLaunchKernelGGL(HIP_KERNEL_NAME(kern), dim3(1), dim3(1), 0,0,6, input_device, value);
hipFree(input_device);
return 0;
}
I compiled the code using hipcc
