Re: [OctDev] [PATCH] CVS-octave-forge and GCC3.2

[Paul K. <pki...@ja...>]

The reason that won't work is because you need to something to catch it.
That requires putting trapping code around each call to superLU to set
the jump return address and reset it when done.  Plus any loops outside
of superLU need to have periodic checks if an interrupt has been triggered.

The macros to do this are in quit.h, but I don't know the exact magic.
Let me know if you are going to persue this, because it is top of my list
(right behind family and work that is, which in this season puts it 
much too far back ;-)
