Well, I'm just completely baffled. The first 5 executable lines
of gfc_conv_array_transpose are
loop = se->loop;
src_ss = gfc_walk_expr (expr);
dest_ss = se->ss;
src_info = &src_ss->data.info;
dest_info = &dest_ss->data.info;
In a gdb session, it appears as if "src_info = &src_ss->data.info;"
is never executed!(?) So, when src_info is referenced in a gcc_assert
some 10 lines down, I get an ICE.
