[Bug c/30958] New: ice for legal code with -ftree-vectorize -Os -mno-sse

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just tried to compile Linux kernel 2.6.20.1
with the GNU C++ compiler version 4.3 snapshot 20070223.

The compiler said

drivers/media/video/pwc/pwc-dec23.c: In function 'pwc_dec23_init':
drivers/media/video/pwc/pwc-dec23.c:305: error: invalid reference prefix
{63368}
