Bug #32064 session_regenerate_id doesn't remove old session file

When regenerating session ID with session_regenerate_id() the file with old ID is kept in the appropriate directory. 

Say that I create a session with session_start() and get ID=abcd. Then sess_abcd is created.

Later I decide to generate a different ID for whatever reason, call session_regenerate_id() and get ID=1234. The old file sess_abcd, although truncated, is still kept in the filesystem. IMO it should be removed at the time of session_regenerate_id() completion.

Reproduce code:
echo "session1 = ".session_id();
echo "session2 = ".session_id();

Expected result:
Only a single file sess_<session2> should be in session dir.

Actual result:
However both files are still there...

Why do you think so?
_All_ session files are removed by garbage collection, if you want to kill your session file explicitly - you have to call session_destroy().
That's expected behaviour and I don't see any bugs here.
