Today's gcc 3.0 crashes on alias

[H . J . Lu]

With today's 3.0 CVS, I got

# cat x.c
const int __new_sys_nerr = 1;
extern __typeof (__new_sys_nerr) _new_sys_nerr __attribute__ ((alias ("__new_sys _nerr")));
# gcc -S x.c
x.c:2: Internal compiler error in make_decl_rtl, at varasm.c:597
Please submit a full bug report, with preprocessed source if appropriate.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.

It is on ia32.
