I'm sick and tired of the universe's ills being blamed on BASH. This is normal behavior for any garden-variety Bourne shell. ksh is the only shell I know offhand which can read out of a pipe -- this behavior can't be relied on unless you know you have ksh.

Some BASH constructs also allow you read text out of a loop. You can't rely on them unless you know you have BASH, of course.

Code:
read A B C <<< $(echo a b c)

You could also reorganize your code to process the relevant variables inside the subshell.
