I don't know when you took a look at you code the last time, but when
I did some time before the COL 3.1 release, there were lots of places
in the reiserfs code where functions assumed that they have valid
arguments when compiled without debugging and did the check explicitly
when compiled with. Given the state the reiserfs code is in I really
prefer to see this option turned on.

Well sometimes it's even better to take a look at the code..

No one said that (and even if I wouldn't believe him).


Of course it doesn't work. We've performed a software upgrade.
