If you are creating x64 applications using Delphi XE2, have Update 2 installed, and are (potentially) allocating more than 4Gb of memory (QC report 100726), then you need the Unofficial fix for QC#100726, or use the latest version of FastMM (see below).
If you use Delphi XE2 (original release) or Update 1, then you don’t have problems in this scenario.
Thanks to FastMM author Pierre le Riche for providing this fix so quickly.
Note that the latest 4.x release of FastMM is now FastMM 4.99 and contains the same fix.
