[Bug c/31254] New: ice for legal code with -O2

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

I just tried to compile recent Linux kernel 2.6.20.3
with GNU C compiler 4.3 snapshot 20070316.

The compiler said

fs/afs/inode.c: In function 'afs_inode_map_status':
fs/afs/inode.c:286: error: type mismatch between an SSA_NAME and its symbol
fs/afs/inode.c:286: error: in statement
vnode_2(D)->vfs_inode.i_mtime = inode_4->i_ctime;
fs/afs/inode.c:286: internal compiler error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make[2]: *** [fs/afs/inode.o] Error 1
make[1]: *** [fs/afs] Error 2
make: *** [fs] Error 2

Preprocessed source code attached. Flag -O2 required.
