Внутренняя ошибка компилятора visual studio 2019

I’m getting a C1001 error while attempting to build in Visual Studio 2019 Version 16.7.2. This is a C++ project that has previously built fine until a change set I am attempting to build today.

The exact error is as follows: (with project specific path redacted)

1>d:work[...](82): fatal error C1001: An internal error has occurred in the compiler.

1>(compiler file 'd:agent_work3ssrcvctoolscompilerutcsrcp2main.c', line 187)

Notes below:

1. The error only happens in Release. Debug builds and runs.
2. If I turn off all optimizations in Release the error goes away.
3. The location where the error occurs seems to be unrelated to recent changes I have made to the project i.e. VS is reporting the error in a translation unit that had been building without problem until unrelated changes in another TU were made.
4. The location where the error occurs seems to not actually be problematic in the sense that if I comment out the implementation of the function there and just return a default value from the function so that the program is syntactically correct, the error occurs in the next the function in the same file.
5. Turning off Whole Program Optimization and Link Time Code Generation does not fix the problem.

  >>Visual Studio 2019 v16.4.4 — Cannot compile simple C++ console App C1001 Internal Error 

  INTERNAL COMPILER ERROR(compiler file file, line number) The compiler cannot generate correct code for a construct, probably due to the combination of an expression and an optimization option. Try removing one or more optimization options and recompiling
  the function containing the line indicated in the error message. You can probably fix the problem by removing one or more optimization options. To determine which option is at fault, remove options one at a time and recompile until the error message goes away.
  The options most commonly responsible are
  /Og and /Oi. Once you determine which option is responsible, you can disable it using the optimize pragma around the function where
  the error occurs and continue to use the option for the rest of the module. 

  For more details I suggest you could refer to the link:
  https://docs.microsoft.com/en-us/cpp/error-messages/compiler-errors-1/fatal-error-c1001?view=vs-2019

  If the error is still there. I suggest you could try to use
  /errorReport. And the flag lets you provide internal compiler error (ICE) information directly to Microsoft.

  Best Regards,

The project was built on my system using boost_1_60 and cmake version 3.14.0. The prompt printed out that the build was successful, and I am able to open the project on Visual Studio 2019.

When I go to compile example_client.cpp , I get the following compiler error:

1>------ Build started: Project: example_server, Configuration: Debug x64 ------ 1>example_server.cpp 1>Unknown compiler version - please run the configure tests and report the results 1>C:UserssmedellinDocumentsopcuafreeopcuaincludeopc/ua/protocol/variant.h(87,1): error C1001: An internal error has occurred in the compiler. 1>C:UserssmedellinDocumentsopcuafreeopcuaincludeopc/ua/protocol/variant.h(87,1): error C1001: (compiler file 'd:agent_work3ssrcvctoolsCompilerCxxFEslp1ctypes.c', line 4589) 1>C:UserssmedellinDocumentsopcuafreeopcuaincludeopc/ua/protocol/variant.h(87,1): error C1001: To work around this problem, try simplifying or changing the program near the locations listed above. 1>C:UserssmedellinDocumentsopcuafreeopcuaincludeopc/ua/protocol/variant.h(87,1): error C1001: Please choose the Technical Support command on the Visual C++ 1>C:UserssmedellinDocumentsopcuafreeopcuaincludeopc/ua/protocol/variant.h(87,1): error C1001: Help menu, or open the Technical Support help file for more information 1>C:UserssmedellinDocumentsopcuafreeopcuaincludeopc/ua/protocol/variant.h(93): message : see reference to class template instantiation 'OpcUa::has_begin_end<T>' being compiled 1>Done building project "example_server.vcxproj" -- FAILED. ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I have tried to fix by adjusting the last if statement of visualc.hpp to

if (MSC_VER > 1922)

instead of

if (MSC_VER > 1900)

Nevertheless, I still get the error listed above.

Я получаю ту же ошибку с VC2012. Настройка свойств проекта Optimization на Disabled (/Od) решила проблему.

В моем решении я удалил выходной DLL-файл проекта и перестроил проект.

Я столкнулся с той же ошибкой и потратил довольно много времени на поиск проблемы. Наконец я обнаружил, что функция, на которую указывала ошибка, имеет бесконечный цикл while. Исправил и ошибка ушла.

В моем случае использовалась статическая лямбда-функция с QStringList аргумент. Если бы я прокомментировал регионы, где QStringList использовался скомпилированный файл, иначе компилятор сообщил об ошибке C1001. Изменение лямбда-функции на нестатическую решило проблему (очевидно, другие варианты могли заключаться в использовании глобальной функции в анонимном пространстве имен или статическом частном методе класса).

Я получил эту ошибку, используя библиотеку boost с VS2017. Очистка решения и его восстановление решили проблему.

У меня была эта ошибка, когда я компилировал цель x64. Переход на x86 позволил мне скомпилировать программу.

Иногда помогает изменение порядка кода. Однажды у меня была эта ошибка в Visual Studio 2013, и это было решено только путем переупорядочения членов класса (у меня был член перечисления, несколько членов строк и еще несколько членов перечисления того же класса перечисления. Он скомпилирован только после того, как я поставил члены перечисления сначала).
