[Bug fortran/37903] [4.3/4.4 Regression] wrong-code for complicated vector subscripts

[mikael dot morin at tele2 dot fr]

------- Comment #4 from mikael dot morin at tele2 dot fr  2008-10-23 22:31 -------
There is this comment at the beginning of gfc_trans_create_temp_array.

/* TODO: Investigate why "if (n < loop->temp_dim)
   gcc_assert (integer_zerop (loop->from[n]));" fails here.  */

This is the case here: n=0, loop->temp_dim=1, loop.from[0]=<lbound(i)>=-1

I don't understand the use of the (n >= loop->temp_dim) condition preventing
the loop bounds from being moved (to be zero-based).

The problem arises farther in the function, when gfc_index_zero_node is used
instead of loop.from, and only the (wrong) loop.to is taken into account.
