mpf_t to 1 billion decimal places

[Sam Kennedy]

I'm trying to calculate pi to 1 billion decimal places, however I get
an error from GMP saying it cannot allocate the memory. I'm running
the 32-bit executable on windows server 2008, the server is 64-bit and
has 6gb of ram.

It appears I cannot use more than 2gb of memory, is there any
workaround for this? I'm compiling with visual studio 2012.

Thank You,
