Description

This is due to MemArena::FindMemoryBase trying to mmap() 0x400000000 bytes (16 GiB) of memory, which overshoots my physical memory by quite a bit. Reducing it to an amount actually available to the OS (~7 GiB) works, though I've only lightly tested it on one game (Rhythm Heaven Fever).

The immediate solution would thus be lowering the mmap'd amount or making it a compile-time option, but admittedly that isn't very elegant.
