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.
