That's the result I get with my 5.9.5, eg no segfault. -- <a href="http://www.tuxedo.org/~esr/">Eric S. Raymond</a> Hoplophobia (n.): The irrational fear of weapons, correctly described by Freud as "a sign of emotional and sexual immaturity". Hoplophobia, like homophobia, is a displacement symptom; hoplophobes fear their own "forbidden" feelings and urges to commit violence. This would be harmless, except that they project these feelings onto others. The sequelae of this neurosis include irrational and dangerous behaviors such as passing "gun-control" laws and trashing the Constitution.
