Details:

Octave checks the timestamps of m-files.  If the timestamp has changed since
the last time Octave compiled the function then the m-file is re-read and
recompiled.

However, on a recent tip (55680de6a897, 9/26/13), I find that the symbol table
becomes corrupted when the timestamp on an m-file in a private directory is
changed.

Example


demo ("quiver", 1)
## In another terminal window, execute 'touch
scripts/plot/private/__quiver__.m
demo ("quiver", 1)
quiver example 1:
 clf;
 [x,y] = meshgrid (1:2:20);
 h = quiver (x,y, sin (2*pi*x/10), sin (2*pi*y/10));
 set (h, 'maxheadsize', 0.33);

quiver example 1: failed
'__add_datasource__' undefined near line 152 column 14


I find that I can restore things if I execute


clear -f


to clear all functions from memory.
