We had the same problem when moving to Service Pack 4 and we found the
cause of the problem.

This is a memory usage re heap allocation.  You may be  freeing some
memory and referenceing it again later.

On Service Pack 4 you could makea registry setting to use the old heap
allocation model.  Apparently an article can be found on the Microsoft
site.  The article does not reference ntdll.dll .  We actually fouynd
the bug in aour code so we din't need the fix.  We were freeing the same
piece of memory twice.

Check you are not updating a screen type component when it is not visible.
ie this does not work under NT but does work under win95

TMyLabel.visible := FALSE;
TMyLabel.Caption := 'My new caption';

Hi all

I have an app running under NT 4.0 sp 4 which went belly up last night with
the following:

EAccessViolation @ etc

Anyone know what ntdll.dll does ? Any suggestions ?

Thanks for any help

We had this some time ago.  It turned out to be an issue with the registry component in Delphi.  We have since switched to a different one and everything works fine.
 
Your mileage may vary...
