From a more official reference, it was also mentioned by Bob Foreman in the NewsGroups:
FYI, this information is also in the latest help file.
In the Help Index, enter “CreateFileMapping error”

Q. When building (compiling) an application, I see a strange error as follows:
CreateFileMapping failed :EXP_PRI.ICOGetLastError
How can I resolve this?
A. As reported on our newsgroups by Oscar Davila, this is an intermittent error.
I meticulously went through all the processes that were running on my system until I identified the culprit. It was The ATI Catalyst Control Center (CCC.exe). Anyone who has an ATI Adapter may be running this service which will cause the error.
Removing this service will solve the intermittent build issue.
