            Bug ID: 299124
          Severity: normal
           Version: unspecified
          Priority: NOR
          Assignee: kdevelop-bugs@kdevelop.org
           Summary: Return type of STL containers' access methods is not
                    resolved (no code completion and DUChain is not built)
    Classification: Unclassified
                OS: Linux
          Reporter: intelfx100@gmail.com
          Hardware: Compiled Sources
            Status: UNCONFIRMED
         Component: Language Support: CPP
           Product: kdevelop

If using a STL container from GCC 4.7.0 (with --std=c++0x), return type of
their access methods like "std::vector<>::at()" is not resolved.
This prevents the DUChain for members' access from being built:

In this example:

Reproducible: Always

Steps to Reproduce:
Sample code:
----
#include <vector>
struct A {
    int fld;
};

std::vector<A> v;
v.at(0).fld = 0;
----
Actual Results:  
1) No auto-completion after typing "at(0)."
2) "fld = 0" is not being highlighted
3) Auto-renaming of "fld" doesn't work.

-> The DUChain for "fld = 0" is not being built.

Expected Results:  
1) Auto-completion of "fld" after typing "at(0)."
2) "fld" in "fld = 0" being highlighted as a variable
3) Auto-renaming "fld" correctly replaces both uses

-> The DUChain for "fld = 0" is expected to build correctly.

GCC version is 4.7.0, and c++0x support is enabled.
