Somewhere in my code I call evhttp_request_own then I put a pointer to the evhttp_request object in an array shared with another thread.
In the other thread, I retrieve the evhttp_request pointer and send a reply with evhttp_send_reply, and when I try to call evhttp_request_free to release memory allocated to the evhttp_request object, it produce a segfault.
Here is the stack trace I get using GDB :
