Maybe the parameter was declared as const? In that case, the refcount  
of the ansistring you pass isn't increased, because the compiler  
interprets the const as "the ansistring will not be changed in any  
way as long as that constructor is running". If it's a value  
parameter, it should work fine (a var parameter obviously wouldn't  
work either).
