           Summary: On 32 bit system (UBUNTU Natty) Cannot open a file of
                    size 5GB
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: critical
          Priority: P2
         Component: libc
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: lsatenstein@yahoo.com


I created a large file that I truncate to 5GB via Truncate command.

I get a NULL return from  fopen("bigfile","rb"); where bigfile is 5GB exactly.

It will work with smaller files 2.5GB. 

Create file with 
truncate -s 5GB bigfile



The function works ok on Debian Squeeze, but not on UBUNTU.  (both are 32bit
versions).  I have not confirmed that it works on Fedora 32bit. 

fopen() works fine with 64bit linux.
