Details:

Loading a 37mb file using textscan In Octave 3.6.4 and Octave 3.8.1 I get the
following error: "error: out of memory or dimension too large for Octave's
index type".

If I replace textscan with dlmread it works fine. Using the command line
debugger (only way I could track down exactly where the error was being
generated), I had tracked down the line it throws the error, it is in
strread.m line 404 which reads 'rxp_wsp = sprintf ("[%s]+", white_spaces);'

Use the following code with the example file in the attached 7z file.

fid = fopen(isofilename);
data=textscan(fid,  '%f %f %f %f %f %f %f %f');
fclose(fid);


I have only used Octave on Windows and I have tried converting the line
endings to Windows one but that doesn't help. I have Matlab at work and this
is a barrier to using Octave to run the script without changing all the
scripts to dlmread.
