First problem: that version is out of date.  But reports to versions 
other than the current one are quite pointless.

No, we're not.  The segfault occurs because the stack you overflow by 
that infinite recursion is the actual CPU stack.  The only remotely 
portable way of checking for stack overflow is to let it occur.  Any 
other way would fail to work, or risk to break scripts that don't need 
to be stopped: those using very deep, but finite recursion.
