Well, I couldn't help it - I had to find a really symmetric testcase. :-)
And here it is (it's a modified version from PR 16971). You can read
it forwards and backwards (well, you have to revert the braces):

=============================================
namespace { ; int tni ; int tni ; } ecapseman
=============================================

The error message mainline used to give was:

:1:C.C:1: error: redefinition of `int <unnamed>::tni'
:1:C.C:1: error: `int <unnamed>::tni' previously declared here
:1:C.C:1: internal compiler error: tree check: expected class 'd', have 'x'
(error_mark) in cp_parser_init_declarator, at cp/parser.c:10717
Please submit a full bug report, [etc.]
