Hello,

The write from address 0xffffe0000 to a file on a 32-bit machine fails, but does'nt fail on 64-bit machine (the process is still 32-bit although it runs on 64-bit).
How can the virtual address of 0xffffffffff600000 exist in a 32-bit process ? (May be I have not made myself clear in explaining the problem?? :-?)
