jit test failure octave 3.8 on windows

[Tatsuro MATSUOKA]

Hello

On the thread concerning GNU Octave in Japan, there was a report for jit 
feature of octave-3.8.0 downloaded from http://mxeoctave.osuv.de/ 

octave-3.8.0-5, octave-3.8.1-rc3
Test

> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end; toc 
Elapsed time is 1.5 seconds. 
> jit_enable(1) 
> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end; toc
(No response)

I have tested the same test on Ubuntu 12.04 LTS (32bit) on octave-3.8.0 built 
by myself on my old notebook .

octave:1> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end; 
toc 
Elapsed time is 4.21553 seconds. 
octave:2> jit_enable(1) 
octave:3> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end; 
toc 
Elapsed time is 0.891052 seconds. 

In this case jit feature worked correctly.

Have anyone met the same phenomena on mxe-build mingw octave ?

I would like confirm before filing bug report.

Regards

Tatsuro
