Huh?

The function_call_stack is maintained every time the user enters / exits
a function, right?

And actually creating the stacktrace from this datastructure should take
a few ms, but only when there is an error, right? I'm sure nobody minds
if their php's _fail_ a little bit slower?

If, however, there was an performance impact, maybe it could be a
configuration-option? or a compile option? I guess most people that need
high performance (and would need to turn it off) have dedicated
development boxes.

Did you look at my patch? Is it not possible to do it this way, or was
there just a small glitch in my code?
