vc | V compiler 's source translated from V to C | Compiler library

while installing truffle on my desktop.An anonymes error ...

first its showing the error related to python which is strange but then i install python now this error `

While debugging a problem in a numerical library, I was able to pinpoint the first place where the numbers started to become incorrect. However, the C++ code itself seemed correct. So I looked at the assembly produced by Visual Studio's C++ compiler and started suspecting a compiler bug.

I was able to reproduce the behavior in a strongly simplified, isolated version of the code:

sourceB.cpp:

i'm trying to install pygame package on my computer which one is not connected to internet.

(env : windows10, python 3.9(anaconda))

so i downloaded a "pygame-2.1.2.tar" file from www.pypi.org and then tried to install it

from cmd with "python setup.py install" commend.

then it shows error message like below

This is a weird bug I'm getting using Xcode 13 and iOS 15.1.1. I've developed a simple app and when I run the app on iOS 15.1.1 (iPhone 13 Pro), before the app launches a white screen (black in case dark mode is ON), is shown, for couple of minutes.

Does anyone know a work around this? This completely disrupts the development process and breaks the flow while testing the app. Build time is within a minute and you have to wait extra time for the white screen to go away.

I've tried the following solutions but it didn't work

1. Removing iOS DeviceSupport and restarting Xcode

rm -r ~/Library/Developer/Xcode/iOS\ DeviceSupport

Edit 1: This is happening only when run button from Xcode is pressed and after it once launches from Xcode and then I close the app and start again from phone it works normal

Deleting DerivedData too did not work

Some code to give reference:

AppDelegate.swift

TL;DR: Debuigging into MFC (CString) header code does not work on both my machines and as far as I can tell this is due to the peculiar way these headers are compiled.

Stepping through MFC header code when entered via disassembly works, but setting brealpoints does not work.

I'm looking for a workaround or at least acknowledgement of my analysis.

System:

• Visual Studio 2019 Professional 16.9.6
• Windows 10 / 1809 Enterprise LTSC

Setup: (I do apologize for this being rather long.)

• Create a Visual Studio 2019 Example MFC Application Project (SDI App)

• Make sure Enable Just My Codeis off under Options -> Debugging -> General.

• Set the build configuration to Debug/x64 (does not make a difference, but let's all stay on the same page)

• Navigate to MFCApplication1.cpp -> CMFCApplication1App::InitInstance()

• Insert a CString init like this:

When i run cargo install wasm-pack on windows 10 64-bit i get this error:

I'm trying a project that uses Qt with MSVC 2019 with Address Sanitizer. I built with Address Sanitizer the project, but didn't rebuild all libs, including Qt.

it crashes inside Qt in resource initialization (with qRegisterResourceData in the call stack).

Is this:

• Misuse of address sanitizer, like, I should rebuild Qt DLLs with it too?
• An issue in Qt I should investigate deeper?
• Known Qt issue?

I've recreated the issue in Widget application created by Wizard by default. The call stack is as follows:

Compiling with cl.exe.

• Using /std:c++17 it compiles with c++14 errors (error C3533: a parameter cannot have a type that contains 'auto').
• Using /std:c++20 it compiles but gives an LNK2019.
• When using /std:c++20, BUT WITH #include moved from serialization.cpp => database.h, it gives a fatal internal compiler error C1001.

database.h:

I want to create a multithread logger in c++ which can be called from c code as well.

This is in my source.cpp file:
