Crash in copy_string

Crashed in copy_string() because m_storage size too much.

What's the size of the vector? Do you restrict the alert queue size? Do you pop alerts regularly?

[lunatichai]

On a first screenshow you can see size 2147483637 Yes lt::settings_pack::alert_queue_size, std::numeric_limits::max() / 2 Yes

[arvidn]

numeric_limits is a template. Is that a limit of 2 billions or 4 quintillions?

Either way, it's probably going to make you run out of memory

[lunatichai]

limit is int (i paste std::numeric_limits< int >::max() but in comment showed only std::numeric_limits::max()) memory 16gb

[arvidn]

1 billion alerts will make you run out of memory unless you pop them at a higher rate than they're produced. I imagine you're not doing that.
