FIX: "An unexpected error occurred" error in the PFMemoryHolder::RegisterMemoryHolder function when you run an MDX query in SQL Server 2012

Microsoft distributes Microsoft SQL Server 2012 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2012 fix release.
Symptoms
When you run a Multidimensional Expressions (MDX) query in an instance of Microsoft SQL Server 2012 Analysis Services (SSAS 2012), the query might fail, and you receive the following error message:
Internal error: An unexpected error occurred (file 'pfiallocator.cpp', line 804, function 'PFMemoryHolder::RegisterMemoryHolder').

Execution complete

Additionally, a minidump file is generated in the SSAS 2012 log folder.

Notes
  • This issue typically occurs if a subcube that is generated has an arbitrary shape set that is below the grain, and that involves a many-to-many or reference dimension relationship.
  • An arbitrary shape set is a set that cannot be easily expressed as a crossjoin set of two sets of attribute members. For example, "{(2004, USA), (2001, Canada)}" is an arbitrary shape set.
Cause
This issue occurs because the SSAS 2012 Storage Engine tries to read a .det file that contains the metadata for the database when you run the query. However, because a path in the metadata is NULL, this causes the issue that is described in the "Symptoms" section.
