/*
* Hi guys,
*
* Compile this without optimization: gcc -g -Wall tst.c -o tst
* and see what happens (SIGFPE). Kernel is 2.1.127 but I think it happens
* on 128 as well (and all others starting from 0.99, or even non-Linux
* systems). What I am asking is - even if it is a CPU bug (all in 386-Xeon range)
* Linux still should be able to work around it (if Solaris can!), should it not?
*
