FPC's default heap manager allocates until the OS reports that the process'
address space is exhausted which for 32-bit processes on Windows without
LargeAddressAware is at around 2 GB. After that you'll receive EOutOfMemory
exceptions.

You can however implement a heap manager that works differently.
