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. Regards, Sven
