I can't reproduce this with msvc versions available on godbolt: https://godbolt.org/z/E8vYWTPf6 Exactly on godbolt,the compilers work well. I test this by myself. Once again, I change to the Microsoft Visual Studio Community 2019 ver. 16.11.18. And compile the program ,the error still exist.

...

Can you provide a complete error log, including source file and line of the error?

soruce file:info.hpp source code line no:145 soruce code:error_info_container_impl * c=new error_info_container_impl; error log: C2259 “boost::exception_detail::error_info_container_impl”: cannot instantiate abstract class, test_boost D:\boost_1_79_0\boost\exception\info.hpp 145

Can you write a simple program that demonstrates the problem on godbolt.org? Looking at the source code, I don't understand why the error_info_container class would be abstract.
