debbuging 4.3 vs 4.5 start_thread() shows different results:
4.3:
182x void thread::start_thread()
183x {
184x thread_info->self=thread_info;
185t> int const res = pthread_create(&thread_info->thread_handle, 0,
&thread_proxy, thread_info.get());
(gdb) p *this->thread_info.pn.pi_
{
_vptr.sp_counted_base = 0x7ffff767e6d0,
use_count_ = 1,
weak_count_ = 2
}
(gdb) n
(gdb) p *this->thread_info.pn.pi_
{
_vptr.sp_counted_base = 0x7ffff767e6d0,
use_count_ = 2,
weak_count_ = 2
}
on 4.5:
(gdb) p *this->thread_info.pn.pi_
{
_vptr.sp_counted_base = 0x7ffff767ead0,
use_count_ = 1,
weak_count_ = 2
}
(gdb) n
(gdb) p *this->thread_info.pn.pi_
Cannot access memory at address 0x30
as you can see, the 4.5 code does bad things.
