...could you provide this? There's insufficient info here to replicate the crash.

The main.cpp can be anything, even nothing. This is what makes me think It's something I've not done.
This one was just:

#include <iostream>
using namespace std;

int main()
{

}


I think it used to work before I switched to multilib repo and then back again to gcc-libs. I'm not sure what else you need??

Given many packages are built using gcc and C++, it is clear we are not replicating the problem...

Do you still have any multilib packages? pacman -Qs multilib

You're compiling c++ code with gcc and not g++? Still shouldn't segfault though...

No multilib packages left. I did everything it says in the wiki about reverting back. It's the only thing I can think of that caused it though. Compiling with g++ spits out the exact same error. I can't compile anything with either.

Compiling c++ code with makepkg -s gives me a different one I've just noticed.

After adding a few directories to $CPATH one by one it eventually gets to the same error.

Well...

fatal error: errno.h: No such file or directory
#include <errno.h>


That is weird! Do you have a /usr/include/errno.h file?

No, I just have /usr/include/linux/errno.h, /usr/include/asm/errno.h, /usr/include/asm-generic/errno.h.

But that error went away when I added /usr/include/linux/ to $CPATH. And after adding a few more it gets back to the segfault. I've reinstalled gcc and gcc-libs and still no change

Oh, I also have /usr/include/err.h

Reinstall glibc.

Also, run "pacman -Qk" and look for packages with missing files.

Thank you! It was as simple as reinstalling glibc. I thought I'd reinstalled all necessary packages. Also, sorry for wasting your time.
