It's a regression introduced between 3.0 and 3.2. 2.95 gives this
error:
g/x> gcc -c x.c
x.c:24: duplicate array index in initializer
x.c:24: (near initialization for `font8x8')
Maybe this gives a another clue as to what goes wrong.

------- Additional Comments From janis187 at us dot ibm dot com 2003-07-24 21:12 -------
The regression in PR 11207 was introduced or exposed by this patch:
--- gcc/gcc/ChangeLog ---
2002-04-26 Alexandre Oliva <aoliva@redhat.com>
* tree.c (tree_int_cst_lt): Compare constants whose types differ
in unsigned-ness correctly.
The regression hunt used the small test case from comment #1 on
i686-pc-linux-gnu. Before this patch, compiling that test case gets:
11207.c:1: array index in initializer exceeds array bounds
11207.c:1: (near initialization for `font8x8')
