Details:
On exiting from Octave 7.0.0 after running a graphics-heavy script, the
following message showed up.
octave:9> exit
WARNING!!! WARNING!!! WARNING!!! WARNING!!! WARNING!!! WARNING!!!
WARNING!!! WARNING!!! WARNING!!! WARNING!!! WARNING!!! WARNING!!!
WARNING!!! WARNING!!! WARNING!!! WARNING!!! WARNING!!! WARNING!!!
YOUR CODE IS RELYING ON DEPRECATED FUNCTIONALTIY IN THE JASPER LIBRARY.
THIS FUNCTIONALITY WILL BE REMOVED IN THE NEAR FUTURE.
PLEASE FIX THIS PROBLEM BEFORE YOUR CODE STOPS WORKING!
The specific problem is as follows:
negative buffer size for jas_stream_memopen
There was no reference to the Jasper library or jas_stream_memopen within the
Octave codebase, only to an unrelated person named Jasper. A web search
indicated it may be related to the Qt libraries used by Octave, so it is being
reported as an early warning of external library changes.
The external source for the Jasper library is here according to a web search:
