Summary: Infinite loop in ConfigureComPlusUninstall

Initial Comment:
Some of my colleagues have reported lockups when
uninstalling two of our products which use some merge
modules I have written.

I was able to trace this in a debugger to a problem
with asmList in ConfigureComPlusUninstall. I think that
the function SortAssemblyListByModule in
cpiasmsched.cpp needs pAsmList->pFirst->pPrev = NULL;
just before it exits. In my case, it pointed to the
last item in the list creating a circular linked list.

This caused a problem in CpiAssembliesUninstall and
CpiRoleAssignmentsUninstall which start at the end of
the list and work backwards. Since there was no NULL at
the start, the for loop never finished.
