[Maxima] RE : Maxima 5.27 crashes

[laurent couraud]

Hi again David,

I did further investigation. And I find this:
The assembly instruction that seems to cause problem is:

pmuludq     mm1,mm7 (multiply packed unsigned doubleword integers)

And this instruction is an SSE2 extension.
My old processor (Intel Celeron 466MHz Family 6 Model 6 Stepping 5 Revision 3)
does not support it.
I don't know where this instruction comes from. I mean does it come from GMP compilation or
does it come from GCL itself.
I suppose everything is compiled with GCC and I guess there is some switches of the compiler
to disable the use of SSE2 extension.

Hope this help.

Laurent.
