Comment (by hapaguy):

 I am running macOS 10.15.1 and using Xcode 11.2. I tried to build OpenBLAS
 @0.3.7 with
 {{{
 $ sudo port -sv install OpenBLAS +gcc9 +lapack
 }}}
 The build fails due to a segfault:
 {{{
 :info:build OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 ./sblat2 <
 ./sblat2.dat
 :info:build Program received signal SIGSEGV: Segmentation fault - invalid
 memory reference.
 :info:build Backtrace for this error:
 :info:build #0  0x10da65564
 :info:build #1  0x10da64c86
 :info:build #2  0x7fff6dc39b1c
 :info:build /bin/sh: line 1: 70219 Segmentation fault: 11
 OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 ./sblat2 < ./sblat2.dat
 :info:build make[1]: *** [level2] Error 139
 :info:build make[1]: *** Waiting for unfinished jobs....
 }}}
 (please see attached `main.log`). This segfault error is similar to that
 reported above.

 I was able to successfully build OpenBLAS @0.3.7 on another Mac - the only
 difference (in addition to the order of installing other ports) is that I
 was running Xcode 11.1.
