Trying to reproduce your example:

123
bash: echo: write error: Broken pipe
ldo@theon:~>
[1]- Done echo 123 > /tmp/fifo
[2]+ Exit 1 echo 456 > /tmp/fifo

The second echo died as soon as the input end of the pipe was closed.


??

I have no errors... and $REPLY is 456


$ uname -r
2.6.24.3vnl

$ echo $BASH_VERSION
3.1.17(1)-release

-----------------

$ echo 123 > /tmp/fifo & echo 456 > /tmp/fifo &
[1] 11408
[2] 11409

$ read -n3 < /tmp/fifo ; echo $REPLY
456
[1]- Done echo 123 >/tmp/fifo
[2]+ Done echo 456 >/tmp/fifo

Did you manage to create an ordinary file called /tmp/fifo?
