Thanks for doing this. Bruce, is this what you expected? Hi Guys, It is not what I expected, but it is not necessarily invalid. mmap implementations are described as *trying* to map the data between between some unmapped pages just so that you can try to extend the mapping. Given that this program is not doing anything else, it really *ought* to be the case that the reference faults. There should be lots of unused virtual address space available. Cheers - Bruce P.S. I should not always rely on Open Group docs. I just saw this in Linux docs: MAP_ANONYMOUS The mapping is not backed by any file; the fd and offset argu- ments are ignored. This flag in conjunction with MAP_SHARED is implemented since Linux 2.4. which means my original version ought to have always worked, but was not portable. Well, now with MAP_PRIVATE, it should be portable, too. :) Anyway, here is some POSIX verbiage that actually implies that the above reference really should fault (though it is colored "optional"): The system shall always zero-fill any partial page at the end of an object. Further, the system shall never write out any modified portions of the last page of an object which are beyond its end. [MPR] [Option Start] >> References within the address range starting at pa and continuing for len >> bytes to whole pages following the end of an object shall result in delivery >> of a SIGBUS signal. [Option End] An implementation may generate SIGBUS signals when a reference would cause an error in the mapped object, such as out-of-space condition. I suppose I could wrap the anonymous mmap call in sigbus protection, but holy moly, just how friggin hard should it be to mmap a bloody text file anyways? Sheesh!!!

Would you please compile and run the attached program on your system

I see the build is somehow succeeding on the buildd's, though... but I don't
