OK, I now see what's wrong: readline was crossed-up. Gnuplot's 
configure script found GNU readline under /usr/local but the build 
linked against Apple's fake readline (libedit.dylib). So bad results 
may be expected.

If I either specify --with-readline=bsd or add -L/usr/local/lib to 
CFLAGS when running configure, I get a consistent build that doesn't 
crash. I'd forgotten about the fake readline business.
