------- Comment #1 from rguenth at gcc dot gnu dot org 2006-10-17 14:09 -------
Confirmed.
We're folding <NULL_TREE> + D.1277->dimD.1247[0].uboundD.1245 -
D.1277->dimD.1247[0].lboundD.1244
here:

so, GFC_TYPE_ARRAY_LBOUND (type, n) is NULL
1301 {
1302 dim = gfc_rank_cst[n];
1303 tmp = fold_build2 (MINUS_EXPR, gfc_array_index_type,
1304 gfc_conv_descriptor_ubound (desc, dim),
1305 gfc_conv_descriptor_lbound (desc, dim));
1306 tmp = fold_build2 (PLUS_EXPR, gfc_array_index_type,
1307 GFC_TYPE_ARRAY_LBOUND (type, n),
1308 tmp);
1309 tmp = gfc_evaluate_now (tmp, block);
1310 GFC_TYPE_ARRAY_UBOUND (type, n) = tmp;
