SYMPTOMS
========
Warnings similar to the following are generated even if you use the warning
pragma to disable the warning:
warning C4786:
'std::rb_tree<CAiSpanningTree<State,std::less<State>>::TransClosureNode,
CAiSpanningTree<State,std::less<State>>::TransClosureNode,std::ident<Cai
SpanningTree<State,std::less<State>>::TransClosureNode,CAiSpanningTree<S
tate,std::less<State>>::TransClosureNode>,std::less<CAiSpanningTree<Stat
e,std::less<State>>::TransClosureNode>>' : identifier was
truncated to '255' characters in the debug information
The code:
#pragma warning(disable:4786)
disables warnings that list the file and line number. For example:
C:\test\Text.cpp(25) : warning C4786:
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.
This problem was corrected in Microsoft Visual C++ .NET.
MORE INFORMATION
================
This warning can be ignored. However, the identifier may not be accessible or
viewable in the debugger.
