Folkert van Heusden a écrit :
I do not see such on i386, so why for x86_64?
So that you know that one of your programs crashed. That's a feature.
This feature could be handy for i386 too.

Since 2.6.18.2 I use this patch. With 2.6.21.1 it still applies altough
with a small offsets. Works like a charm.
