Hi,
Is there a minimal config which reproduces this problem?
I'm building one right now. I noticed immediately that, depending what I delete from the config, I see two distinct issues. Despite running 3.0.x from yesterday with the first fix, I still "sometimes" see "unknown value". At other config constellations, I see "access after free". Particularly, I get the "unknown value" after commenting my last occurence of an rlm_sql_null in the vserver; as soon as I *un*comment that line again, I get "access after free". Maybe the null driver is at fault? As you see below I still instantiate more sql instances than I actually use in the vserver. Maybe that exacerbates the problem. I'm attaching a gdb bt of both instances. It's both in a config with just one vserver, and stripped-down authorize. I'm minimising more gradually, but attach that one vserver config to this mail...
