unodered_map is compiling fine but segfaults on execution

I am having difficulty in understanding why the below program is giving core dump on execution.

   #include <iostream>
   #include <unordered_map>
   using namespace std;
   int main()
   {
       std::unordered_map<int,int> hMap;
       return 0;
   }

There is no compilation warnings or errors but it gives core dump when I execute it. Is this issue related to the platform or compiler? Or am I missing something here?

I am compiling the code using below g++ command

g++ -g -Wall -Werror -std=c++11 -o file file.cpp

Platform is

Linux 3.10.0-1062.4.1.el7.x86_64 #1 SMP Wed Sep 25 09:42:57 EDT 2019 x86_64 x86_64 x86_64 GNU/Linux

Compiler :

gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)

On debugging I am getting the following stacktrace:
