Looks like you found a gcc bug. What happened is that g++ crashed
(SIGSEGV) while processing your file.

It seems to be only in g++-3.3. I tried with g++-3.3 and g++-4.0.2 and
can not reproduce the problem.

The limited stack trace is:

Program received signal SIGSEGV, Segmentation fault.
0x000255fc in pop_everything ()
(gdb) bt
#0  0x000255fc in pop_everything ()
#1  0x0002f834 in cxx_insert_default_attributes ()
#2  0x00072688 in cxx_make_type ()
#3  0x000b7870 in c_common_parse_file ()
#4  0x0022bb8c in rtx_addr_varies_p ()
#5  0x00231224 in rtx_addr_varies_p ()
#6  0x002312e8 in rtx_addr_varies_p ()
#7  0x401ee6e4 in __libc_start_main () from /lib/libc.so.6

(gdb) x/i $pc
0x255fc <pop_everything+808>:   ldw ec(,r20),r3
(gdb) print /x $r20
$1 = 0x0

Perhaps you can try a newer gcc, or file a bug upstream with the gcc
developers. See http://gcc.gnu.org/bugs.html
