Does the same thing happen when you use interp2 instead of imresize (this function is essentially a wrapper for interp2)?

This looks like a problem with an Octave Forge package, not a bug
in Octave. The correct place to report this problem is the
Octave Forge mailing list, octave-dev@lists.sourceforge.net.

A copy of this update to the bug report is being sent to that
list so that they are aware of it. Please follow up there.

This may not be a bug and could be a result of a change in the memory footprint of Octave 3.6.0 compared to 3.2.4.

I am trying to convert code that I have working with 3.2.4 over to octave 3.6.0 (Windows Mingw version).

In my code, I load an large image with imread and then try to resize the image using

AA=imread(T1);
aa1=imresize(AA,0.1);

Under 3.6.0 this produces the following error

error: memory exhausted or requested size too large for range of Octave's index type -- trying to return to prompt.

Were there cahnges to the underlying routines used by imresize that would ahev affected the efficiency of memory use?
