Why didn't you try a newer version?  1.65 is too old.

Hi,

I'm learning to use Boost.asio by going through the tutorials at [1].

However, the listing for "Synchronizing handlers in multithreaded programs" crashes on my Ubuntu. Source listing (about 70 lines) is at [2]. I have given my compilation steps, stack trace from gdb, and boost information below. Can you please advise how I can get this working right?

[1]  https://www.boost.org/doc/libs/1_77_0/doc/html/boost_asio/tutorial.html
[2] https://www.boost.org/doc/libs/1_77_0/doc/html/boost_asio/tutorial/tuttimer5/src.html

I compiled and ran as follows:
$ g++ -g -o timer_5.1 timer_5.1.cpp -lpthread  -lboost_thread
$ ./timer_5.1
Timer 1: 0
Timer 2: 1
Timer 1: 2
Timer 2: 3
Timer 1: 4
Timer 2: 5
Timer 1: 6
Timer 2: 7
Timer 1: 8
Timer 2: 9
Segmentation fault (core dumped)
The backtrace from gdb is:
$ cat gdb_log.txt
