------- Comment #1 from burnus at gcc dot gnu dot org 2010-09-22 08:35 -------
Fails in gfc_trans_scalar_assign for the line:
gfc_add_modify (&block, lse->expr,
fold_convert (TREE_TYPE (lse->expr), rse->expr));
as switch (TREE_CODE (type)) in fold_convert reaches gcc_unreachable.
Hereby,
(gdb) p lse->expr->common.type->base->code
$1 = RECORD_TYPE
(gdb) p rse->expr->common.type->base->code
$2 = RECORD_TYPE
And both types are different, cf.
(gdb) p rse->expr->common.type
$4 = (tree) 0x2aaaad533e70
(gdb) p lse->expr->common.type
$5 = (tree) 0x2aaaad538000

Confirmed as a regression: no ICE for branch fortran-exp revision 158215, ICE
for branch fortran-dev revision 163718.
