QUESTION
Ive discovered a really strange behaviour with std::shared_ptr
in c++.
The following example works perfectly with standard pointers.
However the usage of std::shared_ptr
causes here a segmentation fault. (see the backtrace below)
I know, that accessing a std::shared_ptr
from multiple threads is not safe, therefor I'm using the atomic-operations. Even a classic lock wont solve the problem.
Im using gcc version 6.3.0 20170406 (Ubuntu 6.3.0-12ubuntu2)
with -Wall -O2 -g
and -std=c++17
Does anybody know a solution or why the code is crashing?

Answered 2017-May-24 at 14:18This is a classic problem with smart pointers and list nodes: the destructor of your node is recursive and it ends up running out of stack. This is what that stacktrace shows: stack overflow.
In CppCon 2016: Herb Sutter “Leak-Freedom in C++... By Default.” they discuss exactly this problem.
