Are there any LLP64 platforms except Windows?
Because on Windows the maximum size of the array is 0x7fffffff bytes.
The following line of code:
char buf [0x80000000];
inducts the error on MSVC (32 bit and 64 bit):
error C2148: total size of array must not exceed 0x7fffffff bytes
on ICC 9.1 (32 bit and 64 bit), 10.0 (32 bit and 64 bit):
error: array is too large
char buf [0x80000000];
