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.
