Well, I have compiled and executed Maxima 5.9.3 on
similar systems (Fedora and Redhat EL), and run_testsuite
reports no errors.

That's something to consider. I have compiled 5.9.3
with Clisp 2.34 and it works OK. I don't remember if
earlier versions of Clisp showed any problems.
But maybe you should consider updating Clisp.
Sorry I can't be more helpful,
