I am forced to agree about the fact that optimisation is traditionally
buggy :)
I tried to optimize my system with -O3 and -pipe. So I build myself
a new kernel and a new world, I booted the kernel (I forgot to
install the world)... It booted, windowmaker came up, I executed
a linux-compatible binary (elf) and my system ended up with a boot.
Thank god I didn't do a installworld :) Right now I'm recompiling everything
using only -O and -pipe.
Maybe its the linux-libs that had to be recompiled, but I don't have the time
to sort this out because this machine has to be kind online without
the fear of too much downtime. (I know .. -current .. living on the edge) :)
I'll try to sort it out this weekend.
-Steve
