I tried it after seeing your message.  Indeed I got the same internal gcc
failure.  This is a compiler problem the with the gcc on 10.5.2 (and
10.5.1I think).  I found the same error message on many google hits
outside of
matplotlib.  Your suggestion of compiling with -Os for the two problem files
worked fine for me.
