Francesco Potortì reported on the Octave help list:

http://octave.1599824.n4.nabble.com/Octave-64-bit-for-Windows-can-t-parse-long-hex-integers-td4676253.html

Here I have copied and pasted from Francesco Potortì's post
On Debian: 


>> printf("%x\n", 123456789000) 
1cbe991a08 
>> format long; 0x1cbe991a08 
ans =  123456789000 


On Windows: 


>> printf("%x\n", 123456789000) 
1cbe991a08 
>> format long; 0x1cbe991a08 
ans =  4294967295 


In practice, when parsing a hex literal bigger than 2^32-1, octave reads 
it as 0xffffffff.
