New Comment:
Backtrace information that is returned from debug_backtrace() contains
reference to $this object. So this examle creates circular data
structure.
PHP cannot free circular structures at runtime and does free them on
request shutdown.
So this bug is the same as bug #33595 (recursive references leak
memory).

This not the same situation as #33487
Here, it's not a question of local variable within a method.
And we actually unset the created object.
If I do the same with $this->backtrace = str_pad(' ', 2300); then the
memory is not eaten up.
This occurs only if debug_backtrace() result is affected to a property
of the test object.
