Follow-up Comment #5, bug #50603 (project octave):

OK, I see that.  It's the code near this comment:


          // destLen must be at least 0.1% larger than source buffer
          // + 12 bytes.  Reality is it must be larger again than that.


you are referring to.

Is the compress() function originating from zlib.h?  If so, zlib 

http://www.zlib.net/manual.html

categorizes this function as a utility:

"The following utility functions are implemented on top of the basic
stream-oriented functions. To simplify the interface, some default options are
assumed (compression level and memory usage, standard memory allocation
functions)."

Maybe the "basic stream-oriented functions" have a small memory footprint.

Making a change (and testing) might be a bit to tackle at the moment.  Well,
definitely not a change to make shortly before a release.
