OSX Build failing due to lots of "warning: pointer is missing a nullability type specifier" since XCode 10.2

The error is obvious, too much log so the build was terminated.

I didn’t change anything, it’s an osx image xcode10.2.

Example of ailed job: https://travis-ci.org/github/xbmc/inputstream.ffmpegdirect/jobs/672556449

Lots of warnings like this:

/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/stdlib.h:290:41: warning: pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified) [-Wnullability-completeness]
int      cgetstr(char *, const char *, char **);
                                            ^
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/stdlib.h:290:41: note: insert '_Nullable' if the pointer may be null
int      cgetstr(char *, const char *, char **);
                                            ^
                                             _Nullable
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/stdlib.h:290:41: note: insert '_Nonnull' if the pointer should never be null
int      cgetstr(char *, const char *, char **);

Any ideas what might be happening?

NVM, appears to have self resolved.

EDIT: Correction, works with xcode 10.1 but not with 10.2 image. So still no reason why this started to happen.

Were the images updated?
