clisp testing on linux

[Robert Goldman]

Are you getting that error on the same test (`test-encodings.script`), 
or is it in a different test script?

It would be interesting if it's on the same test, because I am *not* 
seeing this error, and maybe it's causing the segmentation fault.  Would 
you post the context of the error?

Thanks!
