The ChangeLog entry should really be written as:

2004-11-10  Zak Kipling  <zak@transversal.com>

	PR target/18300
	* config/i386/i386.c (classify_argument): Fix infinite loop when
	passing object with 3 or more base classes by value.

testsuite/

	PR target/18300
	* g++.dg/other/infloop-1.C: New test case.



My personal preference would be instead of shadowing the variable i
and having two nested loops with the same index variable, to rename
the conflicting inner loops to use a different variable, such as "j".

Could you retest and resubmit your patch with that change and the
above ChangeLog entry?

Thanks in advance,

Roger
