I built gcc-3.4.3 from the ground up and then built all the support
applications and GNU radio using gcc 3.4.3. I still get the same core
dump if I use the --enable-sse command line argument.
If I REMOVE this setting and build it, everything works fine.
I do have the core files and can do any other tests as desired.
Building all that stuff takes a while, even on a fast machine. I need to
get back to the DOS days and make a RAM drive. :)
