I seem to have some problems with weakref, first I couldn't even pass it to a function, now I tried storing it in an array and it just crashes. Maybe it wasn't designed to be stored like this (though it makes perfect sense to me), but I don't think it should crash so hard. The code to reproduce it looks like this:
class foo
{
}
int main()
{
array<weakref<foo>> arr;
foo f();
arr.push_back(weakref<foo>(f));
return 1;
}
It crashes on push_back, I tried first initializing weakref<foo>, then passing it both by value or reference, always crashed. Here is the callstack:

Unfortunately this goes beyond my ability to debug Angelscript so I just hope someone can see what goes wrong here. If needed I can supply more info - just tell me what.
