Comment (by mouse07410):

 I have clang-11 installed.

 I don't know what caused this bug/problem to manifest -
 {{{fldigi-4.1.17}}} was successfully Macports-installed around Dec 14th.
 Yes I've been using {{{fldigi}}} before, including this current version.
 Macports wants to rebuild it because of some changed dependency.

 I get the same error with GCC10.
