[ci] compilation failing on macOS-latest GitHub Actions jobs using gcc #5589
Description
Description
All CI jobs on macOS started failing some time in the last 12 hours, with the following error.
[100%] Linking CXX shared library /Users/runner/work/LightGBM/LightGBM/lib_lightgbm.so

A linker snapshot was created at:
/tmp/lib_lightgbm.so-2022-11-15-050227.ld-snapshot
ld: Assertion failed: (_file->_atomsArrayCount == computedAtomCount && "more atoms allocated than expected"), function parse, file macho_relocatable_file.cpp, line 2061.
collect2: error: ld returned 1 exit status
make[3]: *** [/Users/runner/work/LightGBM/LightGBM/lib_lightgbm.so] Error 1
make[2]: *** [CMakeFiles/_lightgbm.dir/all] Error 2
make[1]: *** [CMakeFiles/_lightgbm.dir/rule] Error 2
make: *** [_lightgbm] Error 2
This occurs after compiling all objects, at the stage where the linker creates lib_lightgbm.so.
Reproducible example
For example, on #5588, all Python jobs on macOS are failing (link)
And all the two R-package jobs on macOS using gcc.
Additional Comments
It seems like the issue might be "the version of ld included with XCode 14.0 breaks compatibility with gcc": iains/gcc-12-branch#6.
