saa <p5t...@saaworld.com> added the comment: There are bigger problems here. When the code calculates the size to map if size is passed as zero, it simply assigns the 64-bit st_size to the size to mmap. On a 32-bit system, it is obvious that the amount to map must be less than a 32-bit value. The calculation should take into account at least the following two things: 1) it should be the size of the file minus the offset, and 2) it shouldn't ask for an unreasonable amount of memory. I will experiment with this and submit a new patch (and delete the two I've already uploaded) within a couple of days, or at a minimum, provide an update to this bug.
