Description / Steps to reproduce the issue

brief

add_definitions(
    "--save-temps"
)

and set_target_properties(<target>PROPERTIES CXX_STANDARD 20)

can't be used at the same time when i compile with g++.

but building with clang is not matter.

Expected behavior

I hope i can use gcc build code with both --save-temps and c++20 standard;

Actual behavior

I can't use --save-temps and c++20 standard at the both time when I use g++ 14.2.0

Can you provide the code and a separate compiler command to build outside of cmake?

MOYUtianming commented 3 months ago

code

it is the simplest code that can cause the bug, without any other dependencies;


#include<stdio.h>
intmain() {
  return0;
}

command without cmake


g++ ../case/general_test.cpp -g -std=gnu++20 --save-temps -o general_test.bin

it works too, so this segmentation fault maybe directly related to cmake;

file name maybe need to be replaced by yourself;

MOYUtianming/problem_report (github.com)

I have support the whole project in this repository, I can repeat the bug by the following steps:


<open MINGW64;>

<cd to this project's root dir>

mkdir build

cd build

cmake ..

cmake --build .

by the way, if I use 


g++ --save-temps -std=gnu++20 ../case/general_test.cpp -o ./out.bin

the outfile out.bin can be used correctly;

so this error maybe is an error of cmake?
