Re: wierd error

[PETER HOPFGARTNER]

If you use Digital's Fortran, add -fpe3 to the Fortan compilation flags 
(FFLAGS), for GCC, G++ and  G77 
-mieee-with-inexact should be already set.

I just upgraded to 2.0.13 and I get frequent 
floating point exceptions.  I can get one 
anytime I issue the following three commands 
just after startup

Octave, version 2.0.13 (alphaev56-dec-osf4.0d).

octave:1> multiplot(2,2)
octave:2> x = randn(100,1);
octave:3> y = randn(100,1);
error: floating point exception -- trying to return to prompt
     
octave:3> 
     
Changing arguments to randn doesn't change anything.  This is not the only time 
I get such exceptions but this is the only way I can get them predictably.
     
I suspect this is only a problem with DEC machines but can anyone verify this?
