Description Gene Czarcinski 2008-07-11 21:29:22 UTC 
Description of problem:
Attached is an extremely simple program which prints some numbers with
formatting of "%d", "%ld", and "%lld"

On x86_64, I am getting the expected results but on i386 I am getting garbage
when I run it on i386 Fedora 9.

see below

Version-Release number of selected component (if applicable):
Fedora 9 plus (more or less) recent updates

How reproducible:
yes
-------------------------------------------
x86_64:

short   = 2 bytes
int     = 4 bytes
long    = 8 bytes
long long 8 bytes
pointer = 8 bytes

Comment 2 Jakub Jelinek 2008-07-11 21:55:19 UTC 
And what do you expect?  The program is clearly invalid.  You are passing vars
to ... which don't match the expected types from the format string.
POSIX says:
"If any argument is not the correct type for the corresponding conversion
specification, the behavior is undefined." and that's exactly what happened.
