segfault with newer protobuf 3.17.3 and c++14

[jamesoncollins]

I'm working on cross compiling goby3 with a newer version of protobuf.

I've found that I get a segfault during protobuf initialization if I leave the c++ standard set to 14. Changing to 17 makes the segfault go away.

The issue appears to be the same as the one documented here, so it might be an upstream issue.

Is this still a problem? If so, can you suggest a patch to CMake to set C++17 when this is the case?

Closing from lack of info, please reopen if this continues to cause problems.
