bug#47783: 28.0.50; [feature/native-comp] libgccjit.so: error: error invoking gcc driver

[Pankaj Jangid]

I am on macos and after launching Emacs, I get this libgccjit
error. Is this something that I can ignore for now?

Error: Internal native compiler error failed to compile Disable
showing Disable logging
--8<---------------cut here---------------end--------------->8---

Further, there are lots of compiler warnings from different package, as
I use Emacs. That means the native compilation is definitely working
asynchronously. One observation here is that every time this happens the
CPU goes 99% for a short time.

I am not using ‘gcc’. I have yet to successfully build Emacs with
‘gcc-10’ on macos. I did this to build Emacs:

git clone ...
./autogen.sh
CC=/usr/bin/clang ./configure --with-native-compilation
make -j8 # I have 4 core, hyperthreading enabled system

Probably ‘clang’ and ‘libgccjit’ has a problem working together.
