Only 1 line of callstack is shown in my derived class.

Thank you for sharing your wonderful StackWalker library! I encountered an issue which I am not sure if it is a bug. Can you kindly take a look into it?

I downloaded the code from the master branch and used the latest VS2019 to build. When I derived my MyStackWalker class like shown in the README

class MyStackWalker : public StackWalker
{
public:
	MyStackWalker() : StackWalker() {}
protected:
	virtual void OnOutput(LPCSTR szText) override {
        printf("%s\n", szText);
        StackWalker::OnOutput(szText);
	}
};

And I called it this way.

int DummyFunc(int a, int b)
{
    MyStackWalker sw; 
    sw.ShowCallstack();
    return a + b;
}

Only 1 line of callstack is shown on my commandline console.

C:\Users\Shaovoon.Wong\source\repos\TestCallstack\StackWalker.cpp (1140): StackWalker::ShowCallstack

And the ShowCallstack() returns from the if condition at line 1342 of

https://github.com/JochenKalmbach/StackWalker/blob/master/Main/StackWalker/StackWalker.cpp#L1342

    if (s.AddrReturn.Offset == 0)
    {
      bLastEntryCalled = true;
      this->OnCallstackEntry(lastEntry, csEntry);
      SetLastError(ERROR_SUCCESS);
      break;
    }

But when I use the original StackWalker class like this,

int DummyFunc(int a, int b)
{
    StackWalker sw; 
    sw.ShowCallstack();
    return a + b;
}

I can see all the callstack in Sysinternal's DebugView.

C:\Users\Shaovoon.Wong\source\repos\TestCallstack\StackWalker.cpp (1140): StackWalker::ShowCallstack
C:\Users\Shaovoon.Wong\source\repos\TestCallstack\TestCallstack.cpp (22): DummyFunc
C:\Users\Shaovoon.Wong\source\repos\TestCallstack\TestCallstack.cpp (28): main
D:\a\_work\1\s\src\vctools\crt\vcstartup\src\startup\exe_common.inl (79): invoke_main
D:\a\_work\1\s\src\vctools\crt\vcstartup\src\startup\exe_common.inl (288): __scrt_common_main_seh
D:\a\_work\1\s\src\vctools\crt\vcstartup\src\startup\exe_common.inl (331): __scrt_common_main
D:\a\_work\1\s\src\vctools\crt\vcstartup\src\startup\exe_main.cpp (17): mainCRTStartup

But I wish to write the callstack into my log and have my customer send it back to me. I have no access to customer machine and cannot possibly ask him/her to debug on my behalf.

Please kindly advise.

Thank you in advance.

Update: I cannot reproduce this problem on my home PC with VS2022.
