Generic TList<> in Delphi 2009 crash on IndexOf

Question

I\'ve seen many mentions of bugs in Delphi 2009 generics, but never expected something so basic to fail in Update 3, no less. Calling IndexOf on a generic TList or TObjectLi

Answer 1

This is a bug in the default constructor of TObjectList, and I thought it was fixed in update 3. If you're still seeing it, use a different constructor or just update to D2010 or XE, where it's definitely fixed. (And you'll really want to get off of D2009 if you want to work with generics anyway.)
