Hi, I was aware of such a problem. The travis macOS builder got that while ago. https://travis-ci.org/github/crondaemon/wireshark I didn't bisect, but going back in build history, I looks something between 2acbaf584984828855a36105258033020f338c5c and d30a0a2ce7c17f5d695e9ee7647e92d3cc1156bb.

Hi, I'm have been building on macOS Mojave for a while without issues, but for the last few days the build has been broken. I didn't try a git dissect yet to see which commit broke it, but the issue seems to be caused by the usage of the _Nonnull, _Nullable, or _Null_unspecified type specifiers in the 6lowpan dissector.
