I'm using xcode for the C++ part of some iOS app.

When I use std::list, I see its size never go beyond 255 in the lldb. But when
I call the size(), it seems correct inside the container.

Case1:
std::list<int> var1;
var1.resize(300);
// XCode shows 255, see the attachment
// (lldb) frame variable var1 --show-all-children 
// the lldb only unfold the elements to [254]


Case2:
std::vector var1;
var1.resize(300);
// XCode shows 300, see the attachment
// (lldb) frame variable var1 --show-all-children 
// the lldb only unfold the elements to [299]

This can be reproduced on Xcode 4.6 (OS X10.8.4) and Xcode 5.0 (OS X 10.9)
