  Well, it should be completely obvious from all that information to anyone
but a fool that the bug is on line 4373 of your application, where you have
mistyped a semi-colon as a commma, thus turning a statement into a
comma-series expression and thereby extending the scope of the preceding 'if'
to encompass the following subroutine call.

  Either that, or a hippo ate it.
