In config/i386/i386.c, the inner loop at line 1753 uses the same index variable
(i) that is used by the outer loop at line 1741.

Confirmed, it will never show up in ia32 build of gcc, it will only show up in a x86_64 build of gcc.
Here is the code in question (in the function classify_argument):
              for (i = 0; i < n_bases; ++i)
                {
                   ......
                   for (i = 0; i < num; i++)
                     {

This happens in fact twice in this file.
The 3.4 branch and mainline are also affected.
