benchmark: Malloc Assertion Failure with Basic Benchmarking Sample

Hi, I’m still an amateur to this library. I came across this error and wasn’t able find a way to fix it.

I Tried to Run a very basic code to benchmark a function that prints ‘Hello World’. The execution fails with a malloc assertion error.

Environment

Kernel-Version : 3.16.0-4-amd64 Hardware : x86_64 Linux Release : Debian GNU/Linux 9 Page Size : 4096 gcc Version : 6.3.0

Code

#include<stdio.h>
#include<iostream>
#include<stdlib.h>
#include<benchmark/benchmark.h>
using namespace std;

void helloWorld()
{
  printf("Hello World");
}

static void bench_helloWorld(benchmark::State &state)
{
  while(state.KeepRunning())
  {
	helloWorld();
  }
}

int main()
{ 
    BENCHMARK(bench_helloWorld);
    return 0;
}

Error Message

Test.out: malloc.c:2406: sysmalloc: Assertion '(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
