This is a simple reproducer for NVIDIA bug 4139863 (https://developer.nvidia.com/bugs/4139863). The problem has been fixed in CUDA 12.4.0.

Description

Compiling the main() part of a Catch2 application with nvcc in c++20 mode leads to memory exhaustion inside cudafe++, likely due to an infinite loop.

Reproducer

A reproducer can be as simple as test.cu:

#define CATCH_CONFIG_MAIN
#include <catch2/catch.hpp>

Compiling with nvcc in c++17 mode works fine:

/usr/local/cuda-12.1/bin/nvcc -std=c++17 test.cu -c -o test.o

Compiling with nvcc in c++20 seems to hang, and is eventually killed:

/usr/local/cuda-12.1/bin/nvcc -std=c++20 test.cu -c -o test.o
Killed

Investigatinh with nvcc -v -keep shows that the problem is in the cudafe++ step:

/usr/local/cuda-12.1/bin/nvcc -std=c++20 test.cu -c -o test.o -v -keep -keep-dir tmp
...
gcc -std=c++20 -D__CUDA_ARCH_LIST__=520 -E -x c++ -D__CUDACC__ -D__NVCC__  "-I/usr/local/cuda-12.1/bin/../targets/x86_64-linux/include"    -D__CUDACC_VER_MAJOR__=12 -D__CUDACC_VER_MINOR__=1 -D__CUDACC_VER_BUILD__=105 -D__CUDA_API_VER_MAJOR__=12 -D__CUDA_API_VER_MINOR__=1 -D__NVCC_DIAG_PRAGMA_SUPPORT__=1 -include "cuda_runtime.h" -m64 "test.cu" -o "tmp/test.cpp4.ii"

Killed
# --error 0x89 --

The last line of tmp/test.cudafe1.cpp is over 300 MB of repeating std::remove_cv_t< const std::remove_cv_t< const std::remove_cv_t< const ..., which points to some kind of infinite loop inside cudafe++.

---

A preprocessed source file test.cu.ii is also available, to avoid the need for installing Catch2.

It can be used together with the included Makefile to reproduce the crash, and show the start of the infinite-loop line that is being written:

export COLUMNS
make
...
