".zip" file containing "main.cpp", the repro
Using g++ built from source yesterday, getting internal compiler error
(segfault) on a large C++20 project. A preprocessed file (lightly edited and
zipped for file size limit) reproducing the error is attached.
Compiled with:
g++ main.cpp -std=c++20 -mavx2
The output begins with:
