[Octave-bug-tracker] [bug #63791] movfun - high intermediate memory use for moderate data input resulting in out of memory errors

[Rik]

Follow-up Comment #34, bug #63791 (project octave):

There is still an issue where twice as much memory as necessary is being used
by Octave when creating a slice of data.  See the discussion I opened on
Discourse at
https://octave.discourse.group/t/slice-of-array-uses-twice-as-much-expected-memory/4044.

Given that the slice index in this example bug report was 4.1GB, the created
data slice would also be 4.1GB, and the extra unwanted memory allocation is
another 4.1GB for a total of 12.3GB.  It's not wonder a machine with just 8GB
was having trouble with this example.
