Comment (by volgy):

 I have a similar problem with several packages using fftw-3 or
 fftw-3-single (3.3.8) on Catalina.
 I created a minimal program to trigger the crash ({{{Abort trap: 6}}}),
 see the attached file ({{{fftw_crash.c}}}). The FFTW library corrupts the
 stack during the planning phase ({{{fftw_plan_dft_1d}}})

 It seems the problem is with the binary distribution, only. Installing the
 same package from source ({{{port -s install fftw-3}}}) resolves the
 problem.
 Here is some information on my system:
