I trapped the error with DebugDiag, leading to the following output:

I'm not sure what all this tells us. ntdll.dll is a core part of the system that's running fine for over a year, so the problem arises in what ntdll is being asked to do - apparently, to relocate some code into an unwritable part of memory. Why would that happen?
Thanks for any help -

Hi
I'm having an *intermittent* problem on Vista (not seen on XP - so far) when trying to load an external plugin. Right now I'm seeing it with ProcessWrapperPlugin.dll; for the past two weeks - apparently out of the blue - I've been seeing what looks like the same problem when accessing user32.dll after loading other (.NET bridge) libraries.
This is on a 3.7-based customised Internet Explorer plugin VM, which had been working 99% reliably on both XP and Vista for the past 6 months or more.
Switching on the VM's debugging, I see that when LoadLibrary fails it does so with error 998 ("invalid access to memory location").
Once the problem starts it seems to persist, until the system is rebooted. After reboot it typically works ok for a while.
If the problem I'm seeing here is indeed the same as the one with user32.dll (I haven't been able to confirm that yet), it would suggest that the loading of an earlier DLL is causing later ones to fail with 998.
Is anyone else seeing this kind of problem, on Vista or elsewhere?
Many thanks -
Aran
