It's me, the original poster of the thread. I have discovered that when
the Mathematica book tells one to declare the return type of all built-in
functions, when the intended type differs from approximate (scalar) Real
(the default), it means so.
For instance, since I'm expecting a 1D list of integers back from Range[],
I must declare it at the trailing section of Compile[], per:
{Range[_,_], _Integer,1}.
Also, it appears necessary to do so, even for subtle expression forms such
as indices[[m,1]], which in FullForm is Part[indices,m,1]. Hence:
{Part[indices,_,_], _Integer}.
I have found some true bugs with Compile[] in Version 3 beta, but this set
of problems I was having is certainly not among them.
