I have been chasing a FPU register corruption problem on a SMP box. The curruption seems to be caused by FPU emulator code. Is that code SMP safe? If not, what are the volunerable spots? Just thought I'd check before I dive into it .... BTW, I think even with the latest fpu emu patch, the classic fpu/signal problem is still there. I will post in a separate email later. Jun
