_______________________________________________________
Details:
Running 3.2.4 on 32 bit Vista SP2. Tested the following on 2 Vista machines
with 4GB memory and > 2 GB free:
data = zeros(180000, 6, 'single'); % ~ 4 MB
data1 = data(60000:180000, :); % subset of range
detrend(data1, 0); % anything forcing copy crashes
At this point I get the 'error: memory exhausted or requested size too large
. . ." message.
The system is now unstable and "clear all" will frequently crash with 'panic:
Segmentation violation -- stopping myself...' (see GIF attached)
Installed with SSE2 (FFTW3 & ATLAS) and all Octave Forge Libs.
Error occurs in many variations. Seems to coincide with completion of lazy
copy. Error does not occur on full range copies or when the row range is a
only, say, 10000 rows.
