Another idea: In case xdebug overwrites zend_execute() it can set
EG(return_value_ptr_ptr) to point to some local variable then call
original executor and then print pass return_value to caller or destroy
it dependent on previous value of EG(return_value_ptr_ptr).
Thanks. Dmitry.

Sorry, but I think mainly about PHP performance, and of course I didn't know
that you trace return_values it in xdebug.
After the patch, in case if return value is not used we set
EG(return_value_ptr_ptr) to NULL before call to nested execute().
I assume you can just check for (EG(return_value_ptr_ptr)==NULL) before write
it. Will it work for you?
I'm already doing that, so not went really wrong. I am just wondering
whether it would be possible to always have those return values there
through some kind of option.
