check_expected causes segfault.

What steps will reproduce the problem?
1. Compile test-cmockery with 
gcc -std=c99 -I/opt/include -L/opt/lib -lcmockery test-cmockery.c -o 
test-cmockery
2. Run ./test-cmockery

What is the expected output? What do you see instead?
Expected output:
sizeof(unsigned long long): 8
sizeof(unsigned): 4
sizeof(char*): 8
4365541014
70573718
70573718
4365541014
test_demo: Starting test
test_demo: Test completed successfully.
All 1 tests passed

Actual output:
sizeof(unsigned long long): 8
sizeof(unsigned): 4
sizeof(char*): 8
4438503062
143535766
143535766

What version of the product are you using? On what operating system?
Git commit: 1c63f1f479463d9cb5185681cf11799e8efa9092
on Macintosh OS X Mountain Lion 10.8.5

Please provide any additional information below.
By modifying the macro cast_to_largest_integral_type (cmockery.h, line 51), it 
is possible to to remove the error and see the expected output. Specifically, 
changing
#define cast_to_largest_integral_type(value)    \
    ((LargestIntegralType)((unsigned)(value))) 
to 
#define cast_to_largest_integral_type(value)                    \
    ((LargestIntegralType)((unsigned long long)(value)))
removes the error. What is the purpose of casting a pointer (8 bytes on my 
system), to an unsigned integer (4 bytes on my system), then back to an 
unsigned long long (8 bytes on my system)?
