Comment (by kencu):

 I just built libgcc 7.4.0 and cmake 3.16.5 on 10.4 Intel without any
 problem, and everything works fine for me there.

 Also, my other systems rolled back to gcc7/libgcc7 7.4.0 all work.

 Don't forget that on MacPorts, all versions of gcc >= 5 share the same
 libgcc version, so if it's version 7.5.0, every gcc could be expected to
 show the same error.

 My current setups use this
 <https://github.com/kencu/LeopardPorts/tree/master/lang/gcc7> and you can
 please feel free to try that, should you care to.

 All are working correctly at present.
