Thank you very much for your report.

This is a known problem: https://github.com/pkgng/pkgng/issues/263

If you know of any other ports that segfault in the same way, please let
us know by updating that issue on github.  It could be C++ related, but
there are a lot of C++ ports that can be built perfectly well with
SHLIBS enabled, so it's a bit more subtle than that.

	Cheers,
