Broken C++ library in macOS runner

[CendioOssman]

Description

Including <map> for C++ on macOS results in this error in the C++ headers:

...
/Applications/Xcode_14.2.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk/usr/include/c++/v1/chrono:1583:12: error: reference to unresolved using declaration
   static time_t     to_time_t  (const time_point& __t) _NOEXCEPT;
          ^
/Applications/Xcode_14.2.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk/usr/include/c++/v1/ctime:79:1: note: using declaration annotated with 'using_if_exists' here
using ::time_t _LIBCPP_USING_IF_EXISTS;

This error started when the macOS runner was updated from 20230205.1 to 20230214.2. The build tools seem to be the same in both images, though, which makes this very surprising.

I cannot reproduce this locally with the current version of Xcode, which is why this seems to be a GitHub specific bug.

Image version and build link

20230214.2

Is it regression?

Yes

Expected behavior

Code should compile fine, like it did with image 20230205.1:

Actual behavior

Crashes as described above.

Repro steps

Unclear. I have not tried to produce a minimal test case.

Looking at the crashing file, though, it seems like this should be sufficient to trigger the problem:

#include <string.h>
#include <time.h>
#include <map>

Note that I first reported this to GitHub support, as ticket #2023887.

Hi @CendioOssman, seems I cannot reproduce the issue with using just simple repro code example (workflow output).
Could you provide some more clear repro steps?

Also, maybe your issue can be related to this PR - you could simply check if you manually install pkg-config (like brew install pkg-config) at the beginning of the pipeline.

Something has been updated/fixed as if I re-run this failed job, then everything now succeeds:
