Package: octave3.2
Version: 3.2.3-1
Severity: normal

The problem can be reproduced with the following example, composed of the following
two files:
* foo1.m which does nothing special
* foo2.m which creates foo3.m on the fly, and runs it.


----------------foo1.m------------------
1+1
----------------------------------------

----------------foo2.m------------------
system("echo 1+2 > foo3.m");
foo3;
----------------------------------------


The following shell command will fail most of time (but not always) on my machine:

$ rm -f foo3.m && octave foo1.m && octave foo2.m

When it fails, I get:

error: `foo3' undefined near line 2 column 1
error: called from:
error:   foo2.m at line 2, column 1

This has to do with multiple instances of Octave since the following always works
fine:

$ rm -f foo3.m && octave foo2.m

Introducing a long-enough time delay between the two instances of Octave also
solves the problem:

$ rm -f foo3.m && octave foo1.m && sleep 1 && octave foo2.m

I confirm that this bug was fixed in Octave 3.4. Tested on an ext2
filesystem (which has 1s granularity).
