C++ callers misses member pointer method calls via `->`

[LKlei]

Summary

codegraph callers does not report callers for a C++ member function when it is invoked through a typed member pointer.

Environment

• OS: Windows
• CodeGraph version: <paste codegraph --version output>
• Project language: C++
• Command used to index: codegraph init -i or codegraph index

Minimal example

Header:

class CDetect {
public:
    eAlgStateCode Processing();
};

class CDetector {
private:
    CDetect *m_cpAlg = NULL;

public:
    eAlgStateCode Run();
    eAlgStateCode Flush();
};

Source： 

eAlgStateCode CDetector::Run()
{
    eAlgStateCode eDetectCode = m_cpAlg->Processing();
    return eDetectCode;
}

eAlgStateCode CDetector::Flush()
{
    eAlgStateCode eDetectCode =  m_cpAlg->Processing();
    return eDetectCode;
}

eAlgStateCode CDetect::Processing()
{
    ...
}

Expected behavior：
codegraph callers CDetect::Processing

out> CDetector::Run
         CDetector::Flush

Actual behavior
[i] No callers found for "CDetect::Processing", also codegraph callers Processing returens no calls.

Fixed by #454 (huge thanks to @thismilktea for the fix). Your exact example now resolves end-to-end:

codegraph callers CDetect::Processing
→ CDetector::Run
→ CDetector::Flush

Validated at scale on bitcoin-core (1,306 .cpp files indexed) — typed member-pointer call sites went from 0/50 resolved on main to 40,503 cpp method incoming-call edges with the fix landed. The fix covers calls through typed pointers, references, and stack values, including the common case of two classes sharing a method name and call sites embedded in return ptr->m() or Type x = ptr->m() forms.

Will ship in the next release. Closing.
