/bin/bash ../../libtool  --tag=CC   --mode=link gcc  -g -O2 -Wall  -L/opt/gnome2/lib64  -o unix-streams unix-streams.o ../../glib/libglib-2.0.la ../../gobject/libgobject-2.0.la ../../gio/libgio-2.0.la ../../gthread/libgthread-2.0.la 
unix-streams.c: In function ‘reader_thread’:
unix-streams.c:80: warning: ‘nread’ may be used uninitialized in this function
Comment 1 Allison Karlitskaya (desrt) 2009-11-12 04:25:44 UTC 
what version of GCC is this?

it seems *very* clear to me that nread is always initialised.



  do
    {
      total = 0;
      while (total < (gssize) sizeof (DATA))
        {
          nread = g_input_stream_read (in, buf + total, sizeof (buf) - total,


since 'total' is definitely less than sizeof (DATA) at least once

It *was* gcc 4.3.3 in Ubuntu 9.04 (http://packages.ubuntu.com/jaunty/gcc). I've upgraded to 9.10 so I'm no longer able to re-run. I'll check if gcc 4.4.1 has the same issue when I'll start to jhbuild again.

OT the new bugzilla doesn't ask for NEEDINFO resolution??
