Details:

Here is an example demonstrating that the parcellfun function modifies the
load path:


pkg load parallel

d = tempname ;
mkdir(d) ;
addpath(d) ;

p1 = length(path)
p2 = cellfun(@(i) length(path), {1})
p3 = parcellfun(1, @(i) length(path), {1})


If the last three lines are replaced by


p1 = regexp(path, d)
p2 = cellfun(@(i) regexp(path, i), {d})
p3 = parcellfun(1, @(i) regexp(path, i), {d})


the following error message is returned:

error: parcellfun: =: nonconformant arguments (op1 is 1x1, op2 is 1x7)
error: called from
    parcellfun at line 209 column 23



I also noticed that with each (parallel) function call the octave init file
(~/.octaverc) is executed.
