I experience this problem NOT during compilation of PHP, but during EXECUTION of PHP script! It OCASSIONALLY happens, 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 inline comment is ripped of the PHP source, whereas it should be script file name!

This problem also occures randomly when executing php scripts with PHP 4.4.2 and Apache 2.0.54 using mod_php
