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

[Mike Miller]

Follow-up Comment #5, bug #55427 (project octave):

This may simply have to do with internal memory allocation in the zlib
'compress' function, which compresses a single buffer at once. It might be
necessary to switch to using the stream based 'deflate' function to handle
objects over a certain size.

Does 'save -z' work for you on the same system that fails on 'save -v7'? The
v7 format uses 'compress' to compress each element in the Matlab file format,
while 'save -z' uses zlib's 'gzwrite' to write a normal file stream through
the 'deflate' function.
