Process Images above 2G are not saving/restoring

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Modify testers/test.c to malloc a 2G region
2. Run test and try to save
3.

What is the expected output? What do you see instead?
Was receiving "Out of Memory" messages and fixed it by changing xmalloc to use 
a uint64_t. 
Now I'm seeing a segmentation fault when I try to restore. 

What version of the product are you using? On what operating system?
http://dagobah.ucc.asn.au/wacky/cryopid-0.5.9.1-x86_64.tar.gz
Linux #### 2.6.16.60-0.58.1.961.0.PTF.573807-smp #1 SMP Wed Dec 2 12:27:56 UTC 
2009 x86_64 x86_64 x86_64 GNU/Linux

Please provide any additional information below.
Any ideas on the issue?

I changed many int's to uint64_t and am able to save and restore process images 
above 4G now. This program is saving me hours of waiting for an RTL simulation 
to a certain point. Thanks!
