Description:
------------
I believe this is related to bug 28945, but it is in No Feedback mode, and I could not contact him to reopen it.

It OCASSIONALLY happens in my app (it is a large set of classes), and writes to the error log even more amazing thing: here is the sample error log entry:

[12-Nov-2004 15:50:52] PHP Fatal error:  Possible integer overflow in memory allocation (24 * 4294967295 + 0) in /**
   * Returns a SQLDataBase implementation for database $name
   *
   * @param   string $name  database name
   * @return  SQLDataBase   a SQLDataBase implementation for database $name
   */ on line 11

The file that this scratch is ripped from is class definition, where no memory allocation takes place (this is an abstract class)

Reproduce code:
---------------
It is not possible to reproduce this bug, it is a big set of classes (about 170Kb source code), but it is caused by the engine I believe (judging from how the error is reported)

Expected result:
----------------
At least the error log should be:

[12-Nov-2004 15:50:52] PHP Fatal error: Possible integer overflow in memory allocation (24 * 4294967295 + 0) in <filename> on <line number>


Actual result:
--------------
12-Nov-2004 15:50:52] PHP Fatal error:  Possible integer overflow in memory allocation (24 * 4294967295 + 0) in /**
   * Returns a SQLDataBase implementation for database $name
   *
   * @param   string $name  database name
   * @return  SQLDataBase   a SQLDataBase implementation for database $name
   */ on line 11
