Bug#127890: gcc-3.0: ICE in gen_subprogram_die 9463

[<herbert@gondor.apana.org.au>]

Package: gcc-3.0
Version: 1:3.0.2-4
Severity: normal

The following program bombs out on alpha:

$ gcc-3.0  -g -O2 -c a.c
a.c: In function `make_rate':
a.c:16: Internal compiler error in gen_subprogram_die, at dwarf2out.c:9463
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

It was abstracted out from drivers/atm/horizon.c in linux 2.4.17.

I've reproduced it with today's CVS gcc 3.0 branch.  However, it is fixed in
the 3.1 dev branch.
