Help diagnosing gcc7 on MacOS 10.13 and SIGABRT

[Chris Jones]

Hi,

Good suggestion. Certianly would be an issue if different c++ runtimes 
are being mixed.

Easiest solution, if this is the case - Use clang (either system or one 
of MacPorts versions) instead of gcc, as then there will be no c++ 
runtime mis-matches, as these all use the same runtime.
