[cfe-dev] graphviz problem

[Ted Kremenek]

 From Expr.h:

/// StringLiteral - This represents a string literal expression, e.g.  
"foo"
/// or L"bar" (wide strings).  The actual string is returned by  
getStrData()
/// is NOT null-terminated, and the length of the string is determined  
by
/// calling getByteLength().  The C type for a string is always a
/// ConstantArrayType.

This means that using strlen(StringLiteral::getStrData()) is not safe;  
it will just march off the end of the literal until it hits the first  
null character that lies on the heap.
