Trapping F.P. exceptions

[Eyal Doron]

Hi,

   You might know that Octave crashes on floating point exceptions 
on a Dec Alpha. This is getting very annoying: overflows, underflows,
divisions and log of zero, etc, even some assignment operations
(a=1e-305) can crash Octave. Anybody have a solution? John, I know
that there is a problem with gcc, but would it be possible to either:

1) Trap FP errors and just return an error condition, or
2) Save the workspace before crashing?

Thanks,
