c++ emulation issue with std::cout << "Hello World!\n"; #377
Description
I get an error while emulating following MSVC++ code on Linux: std::cout << d << " Hello World!\n";
However, if I change to use printf("%d Hello World!\n", d); it is able to emulate!

Need to debug more too see the actual issue.
Well, Windows always a myth and windows + MSVC. i guess we are lost.

update issue #333 , we should support C++
learn-more commentedon Feb 9, 2021
This is going to be a huge set of functions to support.
BTW this specific function translates to:
public: class std::basic_ostream<char,struct std::char_traits<char> > & __ptr64 __cdecl std::basic_ostream<char,struct std::char_traits<char> >::operator<<(__int64) __ptr64xwings commentedon Oct 6, 2022
Close for now.
We updated the codebase for Qiling and Unicorn since this issue being posted.
Feel free to try the latest version.
