Re-defining view as view in a tal:define statement causes a bus error, instead of an infinite recursion exception. See the attached test case (drop in $INSTANCESHOME/lib/python, copy or link viewcrash-configure.zcml into $INSTANCE_HOME/etc/package-includes, visit /viewcrash).

What happens is that 'view' is called, ending up in a deepening recursion, but somewhere along the way python crashes with a bus error. Apart from the fact that redefining view as view is silly, bus errors indicate a serious C extension or python interpreter bug.
