Delphi 3.0 I have code that works with D3 but <<not>> always with bds4.0. The code in question is a class that has 62 variables that are subclassed from Tmemorystream, it creates an exception when called from the bdsproj file but works just fine after Application.Run is running. The reported error is "EAccessviolation with message 'Access violation at address 004019AB in module LTTview. Write of address 00000000'" Afterwhich it jumps to Getmem.inc line 1627 mov TMediumFreeBlock[edx].PreviousFreeBlock, edi I could go a hundred ways around this problem but I'd like to know what is going on. Thanks, Andrew Back to top aj Guest Posted: Thu Jun 01, 2006 1:19 pm    Post subject: Re: tmemorystream problem Hi I'm posting a follow up. The error seems to be associated with a memory leak.
