There is a known unfortunate limitation on Darwin for SysV shared memory which, incidentally, does not afflict POSIX or mmap'd shared memory.
Hmmm. The article from Chris you have linked does not mention the size of the mem segment you can allocate. Nevertheless - if you compile a 32 Bit binary, there is the limitation Brian mentioned.
You can easily simulate this with a small C program that allocates memory - if you compile it as 64 Bit binary - not problem, if you compile as 32 Bit - crash.
