Hi,

The attached program when compiled using gcc 4.4.3 produces the following
output and never returns :

...
===> Fpga: 865, Thread: 6
===> Fpga: 866, Thread: 6
===> Fpga: 867, Thread: 6
===> Fpga: 868, Thread: 6
===> Fpga: 869, Thread: 6
===> Fpga: 870, Thread: 6
===> Fpga: 871, Thread: 6
===> Fpga: 872, Thread: 6
===> Fpga: 873, Thread: 6
===> Fpga: 874, Thread: 6

I have to kill the process to make it exit. 

The same program when compiled using gcc 4.3.3 and run on the same machine
works fine and produces the correct output.

I compile and run the program on a redhat 4 linux machine with the following
specs:

mawhp2:/home/parvizf/tmp=> uname -a
Linux mawhp2 2.6.9-89.ELsmp #1 SMP Mon Apr 20 10:33:05 EDT 2009 x86_64 x86_64
x86_64 GNU/Linux

mawhp2:/home/parvizf/tmp=> cat /etc/redhat-release 
Red Hat Enterprise Linux WS release 4 (Nahant Update 8)

Thanks in advance for your help.
