Summary0000175: Profile: function or class definition has no entry in profile, and adds to self time in wrong place
Description

While profiling my app, I noticed something odd in the "self" times of some of my scripts.

Let's say file A require_once() file B. File B require_once() file C. File C has a lot of function or class definitions.

In the profiler, no "events" are logged for C.php. Also, almost no time is assigned to C.php, but a lot of time is (incorrectly) assigned to the "self" time of B.php.

Steps To Reproduce

Profile A.php and examine the cachegrind output.

(a.php, b.php, c.php and example cachegrind output atached in zip)

TagsNo tags attached.
Operating SystemWindows XP
PHP Version5.1.2
