[boost] [interprocess] Different processes accessing shared memory in different locations

Hi

Our application has the following scenario using Boost V1.0.52:

1) Process A writes to boost interprocess shared memory. The files
appear at
C:\ProgramData\boost_interprocess\...

2) Process A launches Process B

3) Process B attempts to read from shared memory but fails. It is
attempting to read from:
C:\Users\<username>\AppData\Local\Temp\boost_interprocess\...

This failure only occurs on one single Windows 8 64 bit machine out of
many we have tested. On all other machines, the application works
perfectly.

Please could somebody advise:

What changes to our application could be made to avoid this?
What changes to the machine's configuration (eg. Registry) could be made
to avoid this issue?

Many thanks

Thomas Sanham
