[Octave-bug-tracker] [bug #55427] save -v7 exits with "error compressing data element"

[Mike Miller]

Follow-up Comment #1, bug #55427 (project octave):

I can't reproduce this on Debian with


x = rand (1e5, 1e3);
save -v7 foo.mat


The resulting file foo.mat is about 750 MB instead of the 800 MB saved with
-v6. And if the matrix is all zero instead of random, the resulting file is
about 800 kB.

While compressing Octave's resident memory goes up to about 3 GB, which is
released before the save command returns.
