ah, I thought your were finding strlen < len (because of nulls in *str)
 From reading the headers: len is the amount of data returned.
Since str is not null terminated, as you showed, sooner or later if  
you call strlen(str) you will hit an access violation.
But don't quote me on anything I wrote, I am not an expert in apr!
