Thanks for the hint I was not aware barebox also had these options.

The culprit is show_progress :
[<87f1c340>] (show_progress+0x14/0xf0) from [<87f1e590>] (tftp_send+0x194/0x1e4)
[<87f1e590>] (tftp_send+0x194/0x1e4) from [<87f1e784>] (do_tftpb+0x1a4/0x2d0)
[<87f1e784>] (do_tftpb+0x1a4/0x2d0) from [<87f065e0>] (execute_command+0x30/0x60)
[<87f065e0>] (execute_command+0x30/0x60) from [<87f03d4c>] 
(run_list_real+0x7b4/0x894)
[<87f03d4c>] (run_list_real+0x7b4/0x894) from [<87f03350>] 
(parse_stream_outer+0x104/0x1e4)
[<87f03350>] (parse_stream_outer+0x104/0x1e4) from [<87f03ed8>] 
(run_shell+0x3c/0x5c)
[<87f03ed8>] (run_shell+0x3c/0x5c) from [<87f07870>] (start_barebox+0xe0/0x11c)
[<87f07870>] (start_barebox+0xe0/0x11c) from [<800011d8>] (0x800011d8)

And I get the problem with
arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2011.03-41) 4.5.2
it works with :
arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2010q1-202) 4.4.1

So that seems to be a toolchain issue (adding some printf in show_progress 
make the problem disappear ...).
